1 Cotyledons from the first trimester of gestation were used to isolate a chorionic gonadotropin-like (CG-like) protein by means of ammonium sulfate precipitations (0.17-4.5 M) and gel filtration on Sephadex G-100 and DEAE-Sephadex. DEAE-Dextran chorionic gonadotropin subunit beta 5 Homo sapiens
2 In experiments with cell cultures, it was found that 20 micrograms of protein eluted from Sephadex-DEAE (equivalent to 16 mIU of hCG as determined by RRA) added to the culture medium significantly enhanced (P less than 0.05) progesterone production by the granulosa cells and testosterone production by the Leydig cells.
