Description

Protein Mpb70 is a purified protein antigen, specifically a major secreted protein from *Mycobacterium bovis*, with the CAS registry number 123338-23-8. This compound is of significant value in immunological research and diagnostic development, particularly for bovine tuberculosis. It is primarily needed by biotechnology firms, veterinary diagnostic manufacturers, and academic research institutions focused on mycobacterial diseases and vaccine development.

Application

• Immunodiagnostic Reagent: Key component in ELISA and lateral flow assays for the detection of bovine tuberculosis (TB) antibodies.
• Vaccine Research: Used as a target antigen in the development and evaluation of novel TB vaccines and immunotherapies.
• Specificity Studies: Employed to assess cross-reactivity and improve the specificity of diagnostic tests for *M. bovis* versus other mycobacteria.
• Antibody Production: Serves as an immunogen for generating monoclonal and polyclonal antibodies in host animals.
• Biomarker Research: Utilized in proteomic and serological studies to understand host-pathogen interactions in tuberculosis.
• Quality Control Standard: Acts as a reference standard in the quality control of commercial diagnostic kits.

Quality Control

Our Protein Mpb70 is produced under stringent conditions to ensure high purity and batch-to-batch consistency, suitable for sensitive diagnostic and research applications. Each lot is characterized using advanced analytical techniques including SDS-PAGE, Western Blot, and HPLC. Certificates of Analysis (COA) detailing purity, identity, and biological activity are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted protein solutions should be aliquoted and stored at -70°C to -80°C to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use.
