Abstract
A factor present in the serum of pregnant women is able to inhibit nonspecifically a cellular cytotoxicity reaction. This glycoprotein called P4, is an Α-globulin whose molecular weight is 200,000 daltons bound to albumin. Its isoelectric point is 4.1. By its various characteristics, P4 seems different from other proteins so far described.Keywords
