Comparison of the pregnancy-associated murine protein-2 and human pregnancy-specific 1-glycoprotein

Abstract
Immunological cross-reaction between human pregnancy-specific .beta.1-glycoprotein (SP-1) and pregnancy-associated murine protein-2 (PAMP-2) was demonstrated by line immunoelectrophoresis using antibodies against the proteins raised in hens. The pattern of change of PAMP-2 and SP-1 values in serum during pregnancy was very similar. The murine placental growth-rate corresponded to PAMP-2 levels in maternal serum during pregnancy, indicating placental origin. Apparently, the mouse and its PAMP-2 can be used to study human SP-1.
