Abstract
The present invention relates to the purification of the human chorionic gonadotropin .beta.-core molecule which can then be used as the antigen in the preparation of antibodies to the .beta.-core molecule. The combination of the purified .beta.-core molecule and the antibodies can be used in an immunoassay kit to measure .beta.-core molecules in the presence of structurally similar molecules, i.e., hCG, LH, hCG.beta.-subunit and LH.beta.-subunit. Measurement of the .beta.-core molecule is particularly useful in testing for pregnancy and many malignancies.
