Description

Streptococcal Polysaccharide Ib Group B is a purified capsular polysaccharide antigen derived from *Streptococcus agalactiae* (Group B Streptococcus). This high-purity biochemical is critical for research, diagnostic, and vaccine development applications targeting this significant human pathogen. It is essential for scientists and manufacturers in the pharmaceutical, biotechnology, and in-vitro diagnostic (IVD) sectors who require well-characterized antigens for immunological studies, assay development, and immunoprophylactic solutions.

Application

• Vaccine Research & Development: Key antigen for the development and evaluation of conjugate vaccines against Group B Streptococcus (GBS).
• Diagnostic Assay Production: Used as a coating antigen or standard in immunoassays (ELISA, latex agglutination) for the detection of GBS-specific antibodies.
• Immunological Studies: Serves as a precise tool for studying host immune response, antibody specificity, and serotype epidemiology of GBS.
• Reference Standard: Acts as a purified reference material for quality control and standardization in both academic and industrial laboratories.
• Biochemical Reagent: Employed in structural analysis, carbohydrate chemistry research, and as a substrate for enzymatic studies.
