Pregnancy-specific beta-1-glycoprotein 1 (PSG1) is derived from the syncytiotrophoblast and reaches concentrations in the serum of term pregnant women of 100 to 290 mg/l. As an important component of the human placenta, PSG1's molecular signature within the immunoglobulin (Ig) superfamily contributes to its important role in supporting pregnancy. PSG1 Protein, Human (HEK293, hFc) is the recombinant human-derived PSG1 protein, expressed by HEK293 , with C-hFc labeled tag.
