Anti-TB 38Kd Antigen Antibody [D2G2]

Manufactured by Antibodies.com, this primary antibody is a mouse monoclonal reagent (clone D2G2) raised against the recombinant 38 kDa antigen ofMycobacterium tuberculosis, originally cloned from the virulent reference strain H37Rv. Supplied as a 500 µg lyophilised preparation in 0.01 M PBS (pH 7.0), the antibody is Protein G affinity purified and presented unconjugated, with an IgG2a isotype that minimises non-specific interactions in immunoassays. It is validated for ELISA and Western blot (WB) workflows, where it has been shown to react with and detect the recombinant immunogen in both assay formats, making it a reliable tool for research into mycobacterial virulence factors and tuberculosis diagnostics development. The clone was generated against a recombinant M. tuberculosis protein corresponding to the 38 kDa antigen, a peptide implicated in the regulation of proteins required for bacterial pathogenicity. For long-term stability, the lyophilised product should be stored at -20 °C and, once reconstituted, aliquoted to avoid repeated freeze-thaw cycles; this preserves binding activity across multiple experiments. Intended for research use only, the reagent is reactive against the M. tuberculosis 38Kd antigen target and provides consistent, clone-specific performance in antibody-based detection panels.
