Anti-IgG2b Antibody [KT93]

The Rat monoclonal (KT93) antibody to IgG2b, available from Antibodies.com, is a well-characterized reagent specifically raised against the mouse IgG2b immunoglobulin subclass. Clone KT93 binds the IgG2b heavy chain with defined specificity, allowing researchers to distinguish IgG2b from other mouse IgG isotypes such as IgG1, IgG2a, and IgG3 in immunoassays. This unconjugated antibody is supplied as a 100 µg liquid preparation and is validated for use in ELISA and Western blot workflows. For optimal stability, the antibody should be stored refrigerated at 4°C for short-term use; for extended storage, aliquot and freeze at -20°C, avoiding repeated freeze-thaw cycles. The rat IgG1 isotype of the host antibody makes it compatible with standard anti-rat IgG secondary detection reagents. Researchers commonly employ this antibody when characterizing monoclonal antibody subclass switching, immunoglobulin heavy chain expression in hybridoma supernatants, or isotype-specific responses in murine antibody panels.
