Examination of placental proteins in charge-shift immunoelectrophoresis
Placenta
|July 1, 1983
Three pregnancy-associated proteins, pregnancy-specific beta1-glycoprotein (SP-I), pregnancy-associated plasma protein A(PAPP-A), and placental lactogen (hPL) were examined by charge-shift immunoelectrophoresis. PAPP-A and hPL exhibited hydrophilic properties whereas SP-I was amphiphilic. These observations suggest that SP-I is a cell membrane protein.
