title: Affinity chromatographic purification of the pregnancy zone protein.
abstract: An immunospecific affinity chromatographic method for purification of human pregnancy zone protein (PZP) directly from serum is described. Highly purified goat-anti-human PZP-immunoglobulin was applied as a ligand. Recovery of PZP varied from 56--75%. The impurities constituted maximally 5--10% of the total protein in the eluate. The purification factor was approximately 100.
