Pregnanediol Glucuronide (PDG)-BSA Antigen

A liquid BSA-conjugated antigen preparation from Antibodies.com intended for immunoassay development targeting the progesterone metabolite pregnanediol glucuronide. The 1 mg format is supplied as an Antigen-BSA conjugate in liquid form, making it suitable as a coating or immunogen reagent in ELISA workflows and related antibody production pipelines. Pregnanediol glucuronide is a principal urinary metabolite of progesterone and is widely used as a biomarker in reproductive endocrinology research, ovulation studies, and clinical investigations of luteal phase adequacy. Researchers developing competitive immunoassays for this small-molecule target rely on protein-conjugated derivatives such as this BSA-coupled material to elicit specific antibody responses and to establish immobilized antigen phases for capture-based detection. The liquid form simplifies dilution into standard buffer systems used during plate coating or immunization protocols. Each lot is prepared for research use only and supports consistent assay calibration across experimental runs. Applications include ELISA method development, antibody screening, and assay validation studies related to steroid hormone metabolism. The product is supplied in a vial containing 1 mg of the BSA-conjugated antigen.
