A convenient homogeneous enzyme immunoassay for estradiol is described. Unlike heterogeneous immunoassays, which require time-consuming separation steps or expensive automated systems, homogeneous immunoassays, wherein all reagents are freely suspended in bulk solution, can be simple and fast without costly instrumentation.

Female rats were immunized with mixed 17 beta-estradiol-6-carboxymethyloxime-bovine serum albumin and testosterone-3-carboxymethyloxime-bovine serum albumin. All the animals produced antibodies against the 2 haptens and were better immunized against 17 beta-estradiol than against testosterone. Nevertheless the disappearance of cyclic ovarian function
