Since T-2 toxin is readily metabolized to HT-2 toxin and T-2 and HT-2 toxins are often found together in infected grain, the two mycotoxins are often analyzed together. The combination of T-2 and HT-2 affects many crops, especially grains and feeds such as corn, wheat, barley, millet, corn gluten feed, corn gluten meal, corn DDGS and bran. <br> <br>These mycotoxins can cause illness in animals and humans if diseased grains are consumed. Animals affected by the toxins include swine, dairy cattle, poultry, dogs, cats and horses. Effects of the toxins include digestive disorders, bleeding, edema, oral lesions, dermatitis, and blood disorders. In addition, T-2 toxin is the primary causative toxin in human gastrointestinal toxic leukemia. <br> <br>As food safety awareness has increased in recent years, the European Union (EU) recommended maximum levels for both toxins in food and feed in 2013. To comply with these EU guidelines, grain must be analyzed accurately and reliably. Creative Diagnostics has developed a robust portfolio of T-2/HT-2 Toxin Test Reagents to detect the presence of T-2 and HT-2 toxins in various food products, empowering laboratory researchers, food manufacturers, and regulatory agencies to safeguard public health. <br> <br>The product line includes a comprehensive array of reagents, such as T2-toxin ELISA Kits, HT2-Toxin Standard, T-2 Toxin Test, and RHA™ anti-T-2 toxin monoclonal antibody. For example, the T2-toxin ELISA Kit is designed for quantitative measurement of T-2 toxin in feed, and the T-2 Toxin Test can be used for rapid qualitative analysis of T-2 Toxin in grain/feed.

As an expert in providing solutions to assist virology and microbiology research, Creative Diagnostics has announced the launch of its advanced Respiratory Syncytial Virus Animal Models for researchers and scientists worldwide focused on advancing RSV research and accelerating the development of effective vaccines and therapeutics against RSV. <br> <br>Human respiratory syncytial virus (hRSV) is an enveloped, single-stranded, negative-sense RNA virus that represents a significant public health burden in both developing and developed countries. Scientists have made concerted efforts to develop various animal models to study different aspects of hRSV. However, the high specificity of hRSV for the human host has greatly hindered the development of specialized animal models. In addition, because no single animal model reflects all aspects of this viral infection and disease, a variety of models have been used to study RSV, ranging from rodents and small mammals to large animals and non-human primates (NHPs). <br> <br>With the exception of chimpanzees, nonhuman primates are only partially susceptible to hRSV replication. After infection, nonhuman primates have mild or no clinical signs and generally show mild lung lesions. Cotton rats, mice, ferrets, chinchillas, guinea pigs, hamsters, and newborn lambs are also not susceptible to RSV infection. Additionally, cotton rats and mice have been invaluable in the development of monoclonal antibody prophylaxis for high-risk infants and have provided insights into RSV immunity and pathogenesis. <br> <br>RSV animal models are important tools for studying the complex dynamics of RSV infection, evaluating potential therapies, and developing effective vaccines. With advanced animal modeling technology and unparalleled infectious disease expertise, Creative Diagnostics provides researchers and scientists with reliable respiratory syncytial virus animal models to facilitate the development of therapies and vaccines. Its team of experts can provide clients with the most appropriate RSV animal model based on the infection to be studied and the proposed research hypothesis. <br> <br>Creative Diagnostics offers a full range of services to support RSV animal model research, including study design and execution, pathological analysis and immune response profiling, as well as in vivo pharmacokinetic studies and pharmacodynamics/efficacy/toxicity assessments. These RSV animal model services allow scientists to evaluate the immunogenicity and efficacy of potential RSV vaccine candidates in preclinical studies, investigate RSV pathogenesis to identify novel therapeutic targets, and assess the safety and efficacy of antiviral and immunomodulatory compounds. <br> <br>With extensive expertise in biological research, Creative Diagnostics offers RSV Cotton Rat Models and RSV Mouse Models to advance RSV research, vaccine development, and drug discovery. By providing RSV animal models, Creative Diagnostics aims to help accelerate the development of effective treatments and improve patient outcomes.

Creative Diagnostics, a leading manufacturer and supplier of antibodies, antigens and assay kits, has announced the availability of a comprehensive range of highly validated DNA/RNA methylation antibodies for researchers studying the critical role of methylation in cancer development and progression. These antibodies are designed to facilitate groundbreaking research in epigenetics and cancer diagnostics. <br> <br>To date, at least 17 and 160 chemical modifications have been identified in DNA and RNA, respectively. With more than 70 of the known RNA modifications containing methyl groups, the importance of methylation modifications cannot be overstated. Analysis of nucleic acid methylation and its functional effects is of critical importance to epigenetic researchers. In addition, methylation profiles of the epigenome can be used for disease identification, research and therapeutic development. <br> <br>The detection of methylation in DNA and RNA is particularly important for the diagnosis and treatment of various tumor diseases. CpG island DNA methylation plays a key role in X chromosome inactivation, imprinting, and cancer, and is rare in normal cells and increases with age. There is evidence for hypermethylation of CpG island promoters of tumor suppressor genes such as p16INK4a in melanoma, SET9 in cervical cancer, and p15INK4b in hematologic malignancies. <br> <br>On the other hand, RNA methylation greatly influences tissue development, DNA damage repair, and tumorigenesis and progression by regulating RNA stability. The m6A methyltransferase METTL3 is overexpressed in gastric, colorectal, and hepatocellular carcinomas and promotes cancer cell proliferation by inhibiting the tumor suppressor SOCS2. The m5C methyltransferase NSUN2 is overexpressed in breast and colorectal malignancies. <br> <br>Antibodies against nucleic acid modifications have played a critical role in epigenetics and epitranscriptomics. For example, enrichment of DNA containing 5mC by methylated DNA immunoprecipitation (MeDIP) has been widely used in epigenetics for decades. Additionally, antibody-based sequencing techniques have been widely used for transcriptome studies of a variety of RNA modifications, including m6A, m1A, m5C, and m7G. <br> <br>Antibody-based methods are relatively simple, fast, and cost-effective, but rely on highly specific antibodies to recognize methylated DNA/RNA. The key to generating antibodies that effectively detect RNA modifications is antigen design and antibody validation. Creative Diagnostics now offers a number of highly validated antibodies for DNA/RNA methylation analysis, such as Rabbit Anti-5-methylcytosine (5-mC) monoclonal antibody, clone SN342, Rabbit Anti-5-methylcytosine (5-mC) monoclonal antibody, clone SN342, and Sheep Anti-5-Methylcytosine polyclonal antibody. These antibodies are rigorously validated and optimized for various immunological applications, ensuring consistent and reliable results. <br> <br>The company also offers a wide selection of antibodies targeting different methylation sites, providing researchers with flexibility in their experiments. Creative Diagnostics’ comprehensive portfolio of methylation antibodies are essential tools for advancing the understanding of cancer and developing novel therapeutic approaches. <br> <br>Creative Diagnostics is committed to providing researchers with the products they need for epigenetics and cancer research.
