Anti-TB 38Kd Antigen Antibody [D2G2]

Mouse monoclonal IgG2a antibody clone D2G2 from Antibodies.com recognizes the 38 kDa antigen of Mycobacterium tuberculosis, an immunodominant phosphate-binding lipoprotein that elicits strong humoral responses during active infection. The unconjugated reagent is supplied as a 100 µg lyophilised preparation that reconstitutes cleanly for ELISA and Western blot workflows, supporting immunological characterization of TB-associated antigens in research samples such as mycobacterial lysates and recombinant antigen preparations.

This primary antibody is intended for research use only and supports laboratory investigation of M. tuberculosis antigen expression, B-cell epitope mapping on the 38 kDa antigen, and serological assay development. The IgG2a isotype is compatible with standard anti-mouse secondary reagents, including HRP, biotin, and fluorophore conjugates used in plate-based and immunoblotting readouts. After reconstitution, aliquot the antibody and store frozen to limit freeze-thaw cycles for longer-term use, following routine handling practice for monoclonal IgG preparations.
