CD133 Antibodies

CD133, also known as AC133 or PROML1, is a 5-transmembrane glycoprotein of 120 kDa belonging to the prominin family. It is mainly expressed on primitive cell populations such as CD34 hematopoietic stem and progenitor cells, neural and endothelial stem cells. In association with CD309 (KDR or VEGFR-2), CD133 allows the specific detection of endothelial progenitor cells. CD133 function is unknown although a naturally occurring mutation is associated with degenerative disease in the retina of affected patients.
