Description

Mi22 Protein, Mycobacterium Intracellulare is a purified protein antigen derived from *Mycobacterium intracellulare*, a key member of the nontuberculous mycobacteria (NTM) complex. This high-purity biological reagent is essential for research and diagnostic applications, providing a reliable and specific target for immunological assays. It is primarily utilized by biotechnology firms, diagnostic kit manufacturers, and academic research institutions focused on mycobacterial diseases, immunology, and vaccine development.

Application

• Diagnostic Kit Development: Critical component for ELISA, immunoblot, and lateral flow assays to detect antibodies against *Mycobacterium intracellulare*.
• Immunological Research: Used as a specific antigen to study host immune responses, T-cell reactivity, and antibody profiling in NTM infections.
• Vaccine Research: Serves as a reference antigen in the evaluation of vaccine candidates and immunogenicity studies.
• Quality Control & Standardization: Acts as a positive control and calibration standard in assay validation and laboratory proficiency testing.
• Clinical Studies: Employed in patient serum screening and epidemiological studies to understand the prevalence of NTM infections.
