Steroid specificity of monoclonal Ab3 antibody (mAb3) 1A4 compared with antiprogesterone immunoglobulin M (IgM) 11/64. (a) Inhibition of 11/64 by progesterone-11α–hemisuccinyl (HMS) (•), aetiocholanolone (□) and testosterone (▴). (b) Inhibition of 11/64 by progesterone-11α−HMS (•), progesterone-6β–HMS (▴), progesterone-3–carboxymethyloxime (CMO) (□) and progesterone-21-HMS (▿). (c) and (d) Inhibition of 1A4 by the same steroids as in (a) and (b), respectively. (For the reactivity of Ab1 DB3 with these steroids cf. Figs 2b and 3b.)
