Description

Epidermal Surface Antigen is a high-purity biochemical reagent with the CAS number 158683-68-2. This compound is a critical tool in immunological and oncological research, specifically targeting cell surface markers. It is essential for researchers and manufacturers in the biotechnology and pharmaceutical sectors who require reliable, well-characterized antigens for diagnostic development, antibody production, and targeted therapy research.

Application

• Immunoassay Development: Used as a key antigen for the development and validation of ELISA, Western Blot, and other immunoassays.
• Monoclonal Antibody Production: Serves as an immunogen for generating specific monoclonal antibodies against epidermal cell markers.
• Cancer Research: Employed in studies of epithelial cancers (e.g., carcinomas) to investigate tumor biology and metastasis.
• Diagnostic Reagent Manufacturing: A vital raw material in the production of in-vitro diagnostic (IVD) kits for disease detection.
• Cell Sorting & Identification (FACS): Used in flow cytometry for the identification, sorting, and analysis of specific cell populations.
• Immunohistochemistry (IHC): Acts as a positive control or standard in IHC staining protocols for tissue analysis.
• Therapeutic Target Validation: Utilized in pre-clinical research to validate targets for antibody-drug conjugates (ADCs) or other targeted therapies.
• Academic & Biomedical Research: Fundamental reagent for basic research in dermatology, stem cell biology, and epithelial cell function.
