Description

Antigen 84, Mycobacterium is a highly specific protein antigen derived from Mycobacterium species, identified by CAS No. 161706-51-0. This purified antigen is critical for immunological research and diagnostic applications, enabling precise detection and study of mycobacterial infections. It is an essential reagent for researchers and diagnostic manufacturers in the fields of tuberculosis research, vaccine development, and serological assay production.

Application

• Immunodiagnostic Assay Development: As a key coating or detection antigen in ELISA, lateral flow, and other immunoassays for tuberculosis.
• Tuberculosis (TB) Research: Used in basic and applied research to study host-pathogen interactions, immune response, and pathogenesis of mycobacterial diseases.
• Vaccine Research & Development: Serves as a reference antigen for evaluating vaccine efficacy and immune response in preclinical studies.
• Serological Testing: Employed in the production and quality control of test kits for the detection of anti-mycobacterial antibodies in patient sera.
• Specificity & Cross-Reactivity Studies: Used to determine assay specificity and to identify potential cross-reactivity with other pathogens.
• Clinical Laboratory Use: A component in in-house developed tests (LDTs) for specialized clinical diagnostics.
