anti-PLAP (Placental alkaline phosphatase) mouse monoclonal, F5C2 (C2), purified

PLAP is a tissue specific, throphoblast-derived, 58 kDa, glycosyl-phosphatidylinositol (GPI)-anchored, dimeric, Zn2+ metallated glycoprotein, only found in humans, orangutans and chimpanzees, that catalyzes the hydrolysis of phosphomonoesters into an inorganic phosphate and an alcohol. It is present in the placenta and serum of pregnant women and in high frequency in gynecological and testicular cancers and in lower frequency in other tumors. The three tissue-specific APs in humans, PLAP, germ cell AP (GCAP) and intestinal AP, are 90-98% homologous. Non tissue specific AP is found in kidney, liver and bone. F5C2 binds equally well to all common allelic variants (S,F, FS and I) of PLAP and to some variants of AP from normal human testis, while antibody H7E8 reacts with all variants of AP in normal human testis. Positive control: Human placenta.
