Estradiol-17-beta (7G4) Antibody

Biologically active oestrogen, estradiol-17beta, is an important sex hormone, but also makes an important contribution to the high concentrations of oestrogens which are present in malignant breast tissues. This antibody reacts with estradiol-17beta. No crossreactivity is seen with estrone, estriol, estrone sulphate, 16-ketoestradiol, 2-hydroxyestradiol, progesterone, androstenedione, testosterone, or cortisol when measuring on tritium-labeled steroids in radioimmunoassay.
