Placental proteins and steroid hormones in the soluble fraction of human syncytiotrophoblast plasma membrane

Summary. Placental protein 5 (PP5), pregnancy-specific glycoprotein (SP1), pregnancy-associated ₂-glycoprotein (SP3) and chorionic gonadotrophin could not be demonstrated in appreciable molar quantities in the soluble fraction from microvillous plasma membrane preparations isolated from the syncytiotrophoblast of full-term human placentae. However, progesterone, total oestriol and placental lactogen may have some association with this membrane.
