Description

14K Antigen, Mycobacterium Tuberculosis is a purified protein derivative (PPD) antigen used for the immunological detection of tuberculosis. This high-purity biological reagent is critical for ensuring the accuracy and reliability of diagnostic assays in clinical and research settings. It is primarily utilized by manufacturers of in-vitro diagnostic kits, clinical research laboratories, and public health organizations engaged in TB screening and surveillance programs globally.

Application

• Tuberculin Skin Test (TST) Reagents: A key component in the formulation of purified protein derivative (PPD) solutions for Mantoux tests.
• In-Vitro Diagnostic (IVD) Kits: Used as a critical antigen in ELISA, immunochromatographic (lateral flow), and other serological assays for TB antibody detection.
• Immunological Research: Serves as a standard antigen for studying host immune response, T-cell reactivity, and the pathogenesis of Mycobacterium tuberculosis.
• Vaccine Research & Development: Employed in the evaluation and potency testing of new TB vaccine candidates.
• Quality Control Reference: Acts as a positive control and calibration standard in the production and validation of other TB diagnostic reagents.
• Epidemiological Studies: Used in population-level surveys to assess TB exposure and infection rates.
