Description: The monoclonal antibody 8B6 recognizes human Placental Alkaline Phosphatase (PLAP), a 130 (or 130 with 65 kDa) enzyme expressed by placental syncytiotrophoblastoid cells. This enzyme has slightly different enzyme kinetics from other phosphatases. PLAP can be found anchored to the plasma membrane in addition to the cytoplasm. Expression is found in several germ line cancers; ovarian and testicular. Expression is also present in human embryonic stem cells and bone marrow-derived mesenchymal stromal cells.
This 8B6 antibody reacts with both the Regan and Nagao isozymes.
