Description

Sm25 Antigen CAS NO 136108-05-9 is a high-purity, synthetic peptide antigen designed for advanced immunological research and diagnostic applications. This compound is critical for the development and validation of highly specific immunoassays, including ELISA and Western Blotting, where precise antigen-antibody interaction is paramount. It serves as an essential reagent for researchers and manufacturers in the fields of biopharmaceutical development, clinical diagnostics, and academic research, enabling the study of specific immune responses and the production of monoclonal antibodies.

Application

• Immunoassay Development: Primary reagent for developing and calibrating ELISA (Enzyme-Linked Immunosorbent Assay) kits for specific target detection.
• Antibody Production & Validation: Used as an immunogen to raise polyclonal or monoclonal antibodies in animal models, and for subsequent antibody specificity testing.
• Diagnostic Kit Manufacturing: A key component in the production of in-vitro diagnostic (IVD) devices for clinical and research laboratories.
• Biomarker Research: Employed in proteomics and biomarker discovery studies to investigate disease mechanisms and identify novel therapeutic targets.
• Vaccine Research: Utilized in epitope mapping and the study of vaccine candidates to evaluate immune response elicitation.
• Quality Control (QC) in Biologics: Serves as a reference standard for the quality control testing of therapeutic antibodies and other biological products.
