Human Immunoglobulin G

Purified human IgG protein isolated from normal human serum, supplied by Antibodies.com as a lyophilised powder in a 10 mg vial. The unconjugated preparation serves as a reliable reference standard across immunology workflows, including immunoglobulin quantification, isotype calibration, and use as a blocking agent in immunohistochemistry and Western blot procedures. The lyophilised format preserves activity without cold-chain constraints during transit and supports flexible reconstitution to the working concentration needed for each protocol. Researchers commonly deploy this reagent as a positive control for anti-human IgG secondary antibodies and as a calibrator in nephelometry, radial immunodiffusion, and ELISA standard curves. For laboratory research use only.
