These cutting-edge reagents are designed to enhance food safety and quality control measures.</p><p>Diacetoxyscirpenol (DAS), also known as anguidine, is a type A monotrichothecene mycotoxin. It is a secondary metabolite of fungi of the genus Fusarium and is a major contaminant of cereals and cereal-based foods, potentially causing poisoning in farm animals. DAS has been detected in agricultural products worldwide and remains in products after processing. Studies have shown that consumption of diacetoxyscirpenol induces haematological disorders (neutropenia, aplastic anaemia) in humans and animals. The main adverse reaction following acute and repeated exposure to diacetoxycipranol is vomiting.</p><p>In addition, DAS can cause many chronic and acute effects in animals and humans, such as immunotoxicity, haematotoxicity, pulmonary disease, growth retardation and cardiovascular effects. It can also damage a variety of organs and tissues, including liver, thymus tissue, brain, seminiferous tubules and epididymis. Additionally, DAS can inhibit the synthesis of proteins and DNA, resulting in oral lesions, decreased feed intake, lower serum iron-binding capacity, gastrointestinal lesions and diarrhoea in in various species including pigs, chickens, rabbits, rats, dogs, and calves.</p><p>In 2016, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) evaluated the toxicity of DAS and decided to include DAS in the provisional tolerable daily intake (PTDI) group (WHO/FAO, 2002). To support the accurate and efficient detection of DAS and improve food safety and quality control, Creative Diagnostics now offers a range of sensitive and specific reagents for DAS detection, including Diacetoxyscirpenol Antibodies & Antigens, Diacetoxyscirpenol ELISA Kits, and Diacetoxyscirpenol Screen Tests.

These models are valuable tools in the research and development of vaccines and therapeutics against this emerging global health threat.</p><p>Zika virus is an arbovirus belonging to the genus Flavivirus. It has been little studied in the past because it has been reported to cause only mild symptoms such as fever, joint pain, conjunctivitis and rash. But in 2015-2016, the Zika virus suddenly emerged in Brazil, the United States and Southeast Asia. It spread rapidly, causing cases of miscarriage, microcephaly in newborns and Guillain-Barré syndrome. More worryingly, the Zika virus can be transmitted not only vertically by mosquitoes but also sexually and through blood transfusions.</p><p>Due to the large outbreaks of ZIKA virus-associated disease, the World Health Organization declared ZIKA virus a public health emergency of international concern in early 2016, greatly accelerating the pace of global research into ZIKA virus. Several disease models of Zika virus infection have been established in mice and non-human primates (NHPs) and used for diagnostic, therapeutic and preclinical evaluation of Zika virus vaccines.</p><p>As Zika virus is associated with severe neurological disease and in an effort to prevent and protect against this virus, Creative Diagnostics provides clients with a range of services to develop small and large Zika virus animal models to elucidate the pathogenesis of this emerging disease and to develop vaccines and therapeutic strategies. These ZIKA virus animal models include, but are not limited to, the ZIKV Mouse Pregnancy Model, the ZIKA AG129 Mouse Model and the ZIKA Rhesus Macaque Model.</p><p>For example, mouse models are commonly used to study Zika virus infection due to their genetic tractability and ease of handling, and Creative Diagnostics has been at the forefront of developing and providing high-quality mouse models for Zika virus research. These models allow scientists to study viral replication, tissue tropism and immune responses.</p><p>In addition, rhesus monkeys have proven their value in bridging the gap between mouse models and human infection.

Novel Cyclopiazonic Acid Test Reagents

<p>Creative Diagnostics, a leading manufacturer and supplier of antibodies, small molecule conjugates and critical assay reagents for the analysis of food, feed, environmental and toxicological samples, is excited to announce the release of its <a href="https://www.creative-diagnostics.com/food-analysis/cyclopiazonic-acid.html" target="_blank" rel="nofollow noopener">Cyclopiazonic Acid Test Reagents</a> to help ensure food safety. These reagents are designed to support the development of sensitive and specific immunoassays for the detection of this mycotoxin in food and other matrices.</p><p>Cyclopiazonic acid (CPA) is an indole trichothecene toxin produced by several species of Penicillium, mainly Penicillium camemberti, Penicillium chrysogenum, Penicillium commune, Penicillium viridicatum and Penicillium griseofulvum. Some Aspergillus species, such as Aspergillus flavus and Aspergillus oryzae, can also produce CPA. Several authors have identified peanuts as the main source of this toxin, but studies have also shown that the toxin is present in products such as cereals, prosciutto, cheese, fruit and other nuts.</p><p>CPA is not acutely toxic, with an oral LD50 of 30-70 mg/kg in rodents. The main target of this toxin is the nervous system and it is therefore considered a neurotoxin. Ingestion of CPA results in signs of ataxia and, in extreme cases, death due to spastic paralysis. It can also cause gastrointestinal lesions. The effect of CPA exposure on cells is due to the inhibition of calcium channels in cells. The toxin is a potent and selective inhibitor of calcium ATPase activity.</p><p>Cyclopiazonic acid appears to be toxic only at high concentrations. The symptoms associated to CPA consumption also include anorexia, dehydration, weight loss, immobility and, in the case of near death, convulsions. Few cases of mycotoxicosis with cyclopiazonic acid have been reported because the poisoning is benign, the amount of toxicity is small, and the effects may be masked by concurrent aflatoxin poisoning (some toxicity data may have been derived from the use of aflatoxin-contaminated CPA). To date, there are no national regulations on CPA levels in food products.</p><p>Consumption of CPA-contaminated foods can pose health risks and it is therefore essential to monitor food products for the presence of this mycotoxin. Creative Diagnostics’ new Cyclopiazonic Acid test reagents are highly sensitive and specific and can be used with a variety of analytical methods including ELISA and LFIA. These reagents, such as Cyclopiazonic Acid Antibodies & Antigens, Cyclopiazonic Acid ELISA Kits, and Cyclopiazonic Acid Screen Tests, are also easy to use and require minimal sample preparation.</p><p>Creative Diagnostics is committed to providing high-quality research reagents and diagnostic solutions to support the development

High-Affinity Anti-Adenovirus Monoclonal Antibodies for Research and Assay Development

<p>Creative Diagnostics, a leading manufacturer and supplier of antibodies, antigens and assay kits, is pleased to announce the availability of its highly specific <a href="https://www.creative-diagnostics.com/Anti-Adenovirus-hexon-protein-MAb-FITC-Conjugated-129647-491.htm">Anti-Adenovirus Monoclonal Antibody</a>. This research tool offers exceptional accuracy and sensitivity for the detection of adenoviruses in various applications such as IF, ICC, and ELISA.</p><p>Adenoviruses (members of the family Adenoviridae) are medium-sized (90-100 nm), nonenveloped viruses with icosahedral nucleocapsids containing a double-stranded DNA genome. The name derives from the first isolation of an adenovirus from human adenoids in 1953. Adenoviruses DNA viruses are generally widespread in nature with a variety of vertebrate hosts. In humans, 88 human adenoviruses have been identified in seven populations (A through G) and more than 50 different adenovirus serotypes have been identified, causing a wide range of diseases from mild respiratory infections in young children to life-threatening multi-organ disease in people with compromised immune systems.</p><p>Culture is the gold standard for diagnosis of adenovirus infection. However, culture results can take up to 3 weeks. Serological tests have a faster turnaround time but may not be as sensitive as culture. Because of the clinical importance of rapid laboratory diagnosis, direct detection of viral antigens in nasopharyngeal secretions, feces, or both is used as the primary diagnostic test for adenovirus infection.</p><p>Immunofluorescence (IF) was the first method used for rapid diagnosis of respiratory infections caused by viruses. In the hands of an experienced microscopist, the method is both sensitive and specific. Individual specimens can be tested on arrival at the laboratory and results are available within a few hours. The most important aspect of IF is specimen collection and processing, and a sufficient number of infected respiratory epithelial cells should be obtained.</p><p>Adenoviruses are a common cause of respiratory illness, and effective research tools are crucial for understanding and developing treatments for these infections.

The new anti-virus testing solution offers a valuable tool for researchers working on influenza virus characterization, vaccine development, and general viral diagnostics.</p><p>Certain viruses agglutinate red blood cells in certain animals, a process known as viral hemagglutination. HA test is designed to infer the presence of the virus in the material being tested and to determine whether this response is specific. It is a well-established method that is widely used in influenza vaccine, diagnostic and surveillance to measure virus and antibody titers and to monitor influenza subtypes.</p><p>Hemagglutination occurs when the hemagglutinin protein on the surface of the influenza virus binds to a serine on red blood cells (RBCs). Similarly, when sufficient numbers of virus and RBCs are present, the virus particles act as a bridging agent, forming a network that connects the RBCs, resulting in hemocoagulation.</p><p>The hemagglutination assay is the most commonly used method for detecting influenza virus, adenovirus, rabies virus, and many other microorganisms. It is the basis for a wide range of veterinary and life science diagnostic tests. HA analysis is simple, uses relatively inexpensive and commonly available instruments and consumables, and provides results within a few hours. The method has been well validated in many laboratories around the world and has a degree of reliability, comparability and standardization.</p><p>In addition, the ability of viruses to agglutinate RBCs can be inhibited by specific antibodies, leading to the development of the hemagglutination inhibition (HAI) assay. The HA-HAI test allows the identification of unknown viruses in known sera and the titration of antibodies in unknown sera with known viruses by determining the level of the corresponding antibodies. The hemagglutination assay, used in conjunction with interactions, produces a visible network showing the relative concentrations of viruses and antiviral antibodies.</p><p>Creative Diagnostics now offers Hemagglutination Assay services and customized early detection solutions to life science researchers focused on antiviral and infectious disease diagnostics.

Plaque Reduction Assay Services to Advance Antiviral Research

<p>As an expert in providing solutions to assist virology and microbiology research, Creative Diagnostics is proud to announce the launch of its comprehensive suite of <a href="https://antiviral.creative-diagnostics.com/plaque-reduction-assays.html">Plaque Reduction Assay</a> services to support antiviral research. These new solutions offer researchers a powerful and well-established method for evaluating the efficacy of antiviral compounds.</p><p>Normal cells can absorb reactive dyes during metabolism, but when the cells are infected with a virus, they lose their ability to absorb the dye, resulting in the formation of colorless plaques. When a virus is neutralized by a specific antibody and then infects a cell, the number of cellular plaques formed decreases accordingly. Therefore, the titer of the antibody that neutralizes the virus can be calculated from the number of cellular plaques.</p><p>The Plaque Reduction Assay measures the efficiency with which the virus forms plaques in the presence of different concentrations of the assay. The time required for plaque visualization depends on the kinetics of viral replication and ranges from 24 hours to several weeks. Because plaques must be at least 1 mm wide to be accurately scored (especially by the naked eye), this analysis is typically performed on 24-well or 6-well plates, as any smaller wells may compromise readability and resolution.</p><p>The plaque reduction neutralization test (PRNT) is a variant of the plaque reduction assay and is considered the gold standard for detecting neutralizing antibodies to certain viruses, such as dengue virus. The basic design of the PRNT is to generate virus-antibody interactions in test tubes or microtiter plates and then apply the mixture to virus-sensitive cells to measure the effect of the antibody on virus infectivity.</p><p>PRNT is a versatile tool in virology with applications in diagnosing viral infections, characterizing toxins, and vaccine development. It can be used to detect antibodies in a patient’s serum or identify viruses in diseased tissue, aiding in diagnosis. PRNT can also be utilized with antitoxin serum to identify and quantify bacterial toxins in pathological material. Furthermore, it is a valuable technique for determining the potency of antiviral serums and antitoxins, as well as identifying and classifying newly isolated viruses.</p><p>As a solution provider for virology and microbiology research, Creative Diagnostics offers comprehensive Plaque Reduction Assay services (e.g., PRNT) to empower researchers to accelerate breakthroughs in the field of virology. The company is dedicated to providing antiviral testing and customized early detection solutions to life science companies working in the field of antiviral and infectious disease diagnosis.</p><p>For viruses with only minor cellular lesions or viruses that take a long ti

Norovirus VLP Antigens to Support Vaccine Research

<p>Creative Diagnostics, a leading manufacturer and supplier of antibodies, antigens and assay kits, is pleased to announce the availability of its new line of <a href="https://www.creative-diagnostics.com/new-norovirus-vlp-antigens.htm">Norovirus VLP Antigens</a> to accelerate in vitro diagnostics and vaccine research. These new antigens have been validated to a high level of confidence using electron microscopy.</p><p>Norovirus is a non-enveloped, positive-sense, single-stranded RNA virus of the family Caliciviridae and is the leading cause of non-bacterial acute gastroenteritis worldwide. The infection is characterized by non-bloody diarrhea, vomiting and abdominal pain. The stability of viral particles is of particular interest because noroviruses are transmitted by the fecal-oral route and they can persist in the environment. Studies of the assembly and degradation of norovirus capsids have relied heavily on norovirus-like particles.</p><p>The norovirus genome is 7.4-7.7 kb in size and has three open reading frames (ORFs). Nonstructural proteins, such as RNA-dependent polymerase (RdRp), are encoded by ORF1, while structural proteins are encoded by ORF2 (VP1) and ORF3 (VP2). Structural analysis of noroviruses has shown that each viral capsule consists of 90 dimers of VP1 with T = 3 icosahedral symmetry. Various expression systems have been developed to produce viral capsids in the form of virus-like particles (VLPs).</p><p>Noroviruses are classified into genomic groups and genotypes based on the amino acid diversity of the VP1 protein. According to this system, the genus Norovirus is divided into 10 genomes (GI-GX) and 49 genotypes (9 GI, 27 GII, 3 GIII, 2 GIV, 2 GV, 2 GVI, and 1 each of GVII, GVIII, GIX [formerly GII.15 ], and GX), of which the genomes known to be infectious to humans include GI, GII, GVIII, and GIX. GII.4 is of particular importance as it has caused numerous outbreaks worldwide over the years and is believed to be the primary cause of human infections.</p><p>Creative Diagnostics now offers a series of yeast-expressed Norovirus VLP antigens for in vitro diagnostic and vaccine studies, including Recombinant Norovirus GI.1 VLP, Recombinant Norovirus GII.3 VLP, and Recombinant Norovirus GII.17 VLP. These antigens have been validated with high confidence by electron microscopy and provide researchers and diagnosticians with a powerful tool for studying and detecting Norovirus infections. Creative Diagnostics’ team of experts is also available to assist researchers in selecting the most suitable antigens for their specific studies.</p><p>The purified Norovirus VLP Antigens are an example of Creative Diagnostics' commitment to providing innovative and reliable products to the research and diagnostic communities. Its team has worked diligently to develop antigens that are not only highly specific but also offer excellent sensitivi

High-Affinity Anti Venom Antibodies for Research Applications

<p>Creative Diagnostics, a leading manufacturer and supplier of antibodies, antigens and assay kits, is pleased to announce the availability of its high-affinity <a href="https://www.creative-diagnostics.com/anti-venom-polyclonal-antibody.htm" target="_blank" rel="nofollow noopener">Anti Venom Antibodies</a> to researchers studying snakebite envenomation. These antibodies hold immense potential for improved snakebite treatments.</p><p>Snakebite envenomation is considered a neglected tropical disease that affects tens of thousands of people each year. Snake venom is an extremely complex mixture consisting mainly of proteins (±90-95%), in addition to peptides, carbohydrates, fragments of nucleic acid derivatives, metal ions, biogenic amines, lipids and free amino acids, which have different biological activities.</p><p>In general, viperid venoms are cytotoxic, hematotoxic, and occasionally myotoxic due to the fact that snake venom metalloproteinases (SVMPs) weaken capillaries and blood vessel walls, leading to hemorrhage. SVMPs and phospholipase A2 (PLA2) also cause tissue damage at the site of the bite, resulting in muscle weakness and tissue necrosis. On the other hand, elapid venoms (and a small percentage of viperid venoms) contains neurotoxins (which primarily cause systemic neurotoxicity) that block neuromuscular signaling. These toxins eventually block signaling to the lung muscles, causing respiratory paralysis and death.</p><p>Currently, the recommended treatment for snakebite is the use of antivenom or serum therapy, which treats snakebite by neutralizing the venomous toxins produced by snake venom. The most important clinical determinants in the treatment of snakebite are the type of antivenom to be used and the dose of antivenom. The specificity and dosage of antivenom depend on the accurate diagnosis of the snake. This requires the use of immunology-based assays, such as ELISA, to detect and quantify specific venoms to confirm the identity of the snake. In addition, the free venom of the patient is measured after therapy to determine if sufficient antivenom has been administered. Immunoassays can also be used to evaluate the cross-reactivity of antivenoms.</p><p>Effective antivenom therapy is critical to saving lives, but accurate diagnosis and appropriate antivenom selection are often challenging. Creative Diagnostics now offers a comprehensive portfolio of anti venom antibodies that target a broad range of toxins found in snake venom, providing researchers with valuable tools for the development of new and improved antivenom therapies. These new anti-venom polyclonal antibodies are specifically designed for research applications and are not intended for diagnostic use, such as the Sheep Anti-Vipera l atastei Venom PolyclonalAntibody (DPAB-JX2371341).</p><p>Creative Diagnostics is committed to advanc
