Human pregnancy-associated plasma protein A (PAPP-A) binds to heparin-Sepharose. This affinity chromatography preceded by molecular sieve chromatography provides a simple two-step purification procedure of PAPP-A from late pregnancy plasma. One hundred percent of the applied PAPP-A was recovered, with more than 40% being electrophoretically homogeneous after the two procedures. The remaining PAPP-A could be purified by negative affinity chromatography on anti-total human serum immobilized on agarose.
