Human Immunoglobulin G (IgG) Antigen >98%

This purified Human Immunoglobulin G (IgG) antigen from Antibodies.com is presented as a lyophilized powder in a 100 mg vial. The target is Human IgG, with purity verified above 98% by SDS-PAGE.

Researchers use this antigen as a reference standard or coating reagent in ELISA and Western blot (WB) workflows. It serves as a positive control for anti-IgG antibody detection, a calibrator in quantitative IgG immunoassays, and an immunogen for raising anti-human IgG reagents.

Reconstitute the lyophilized pellet in an appropriate buffer such as PBS prior to use. To preserve activity across the shelf life, aliquot the reconstituted product, store refrigerated, and avoid repeated freeze-thaw cycles.
