A substance having an inhibitory effect on the production of human choriogonadotropin (hCG) is described, which comprises a protein isolated from human decidual cells with a preliminary amino acid analysis and a molecular weight of about 7,000 to about 10,000 daltons, and useful for use in inhibiting production of hCG in vivo or in vitro, may be measured as an indication of a cause of hCG inhibition, or used in the treatment of hCG-secreting tumors. |
