CD133/2 antibodies

CD133/2 antibodies

Clone: 293C3
CD133 is a 5-transmembrane cell surface antigen with a molecular weight of 117 kDa. It is expressed on a subset of CD34
stem and progenitor cells in human fetal liver, bone marrow, cord blood, and peripheral blood but is not found on mature blood cells¹. Additionally, CD133 is expressed by a small portion of CD34
cells in these tissues.
In contrast to the CD34 antigen, CD133 is not expressed by late progenitors such as pre–B cells, CFU-E, and CFU-G²
Clone 293C3 recognizes epitope 2 of the CD133 antigen.
