| Product Name | Chorionic Gonadotropin, Human, alpha (hCGa) |
|---|
| Description | Purity ~98% (SDS-PAGE). Human Chorionic Gonadotropin (HCG) is a glycoprotein, which is secreted in large quantities by normal trophoblasts. It is present only in trace amounts in non-pregnant urine and sera but rises sharply during pregnancy. HCG is composed of two non-identical, non-covalently linked polypeptide chains designated as the a-and b-subunits. The a-subunit of HCG is nearly identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), and luteinizing hormone (LH). A germ cell tumor which is positive for cytokeratin, placental alkaline phosphatase (PLAP), and HCG but negative for EMA and AFP is probably a choriocarcinoma. Source: Human Chorionic Gonadotropin alpha subunit (hCG-a), from urine. Molecular Weight: ~14.5kD Activity: 1mg protein/mg powder (OD280nm). |
