We provide a comprehensive selection of antigens meticulously purified and validated for in vitro diagnostic (IVD) applications. Our curated collection includes antigens sourced from various pathogens, including viruses, bacteria, and other infectious agents, as well as tumor-associated antigens and autoimmune markers. These antigens serve as critical components in IVD assays for diagnosing infectious diseases, monitoring immune responses, and detecting cancer biomarkers. Rigorously characterized for purity, stability, and specificity, our antigens ensure the accuracy and reliability of diagnostic tests. Researchers and diagnostic professionals trust our high-quality antigens to develop robust and sensitive IVD assays that facilitate early disease detection, patient management, and treatment monitoring.
