The subunit structure of the testicular LH/hCG receptor was studied by a chemical cross-linking technique. Leydig cells isolated from rat testis were incubated with {sup 125}I-hCG, following which the bound {sup 125}I-hCG was covalently cross-linked to the receptor on the cell surface with a cleavable or a non-cleavable cross-linking reagent. The hormone-receptor complex was extracted and then either subjected to gel permeation chromatography under nondenaturing conditions, or resolved by SDS-polyacrylamide gel electrophoresis, followed by autoradiographic analysis. The ovarian LH/hCG receptor was studied with luteal cells from pseudopregnant rats. Purification of the receptor was achieved by ligand affinity chromatography following detergent solubilization of the plasma membrane. The purified hCG receptor displayed properties identical to the membrane bound receptor with regard to binding specificity and affinity, and exhibited a molecular weight of approximately 130,000 dalton.
