Anti-Estradiol (E2) Antibody

Mouse monoclonal IgG1 reagent from Antibodies.com recognises 17β-estradiol, the most biologically active endogenous estrogen and a key steroid hormone involved in reproductive and metabolic regulation. The antibody is supplied at 1 mg per vial after Protein G purification, in an unconjugated format that supports direct use or downstream labelling.

Validated for ELISA workflows, the antibody enables detection of estradiol in research samples from studies of ovarian function, menstrual and estrous cycle hormone dynamics, pregnancy, menopause, and estrogen-receptor signalling in hormone-responsive tissues. It is widely applied in veterinary endocrinology, reproductive toxicology, and screening programmes for estrogenic endocrine-disrupting compounds in environmental samples.

The murine host, monoclonal clonality, and IgG1 isotype support consistent batch-to-batch performance, while the unconjugated format gives researchers freedom to couple the antibody with HRP, biotin, fluorophores, or other reporters to suit a chosen detection platform. Storage at refrigerated temperatures with protection from light preserves activity, and aliquoting is recommended for repeated use to limit freeze-thaw cycles.
