Anti-TRA-1-85 Antibody, blood group Antigen Ok(a), clone TRA-1-85

35-69 kDa

The high-frequency blood group antigen Ok(a) is carried on a red cell membrane glycoprotein (gp) of 35-69 kDa that is widely distributed on malignant cells of different origins. Immunostaining of hemopoietic cells and a range of normal human tissues demonstrated a wide distribution of the Ok(a) gp that appears to be nonlineage-restricted, although certain tissues show differentiation-related expression. This clone can be used to monitor contamination of human Embryonic Stem cell cultures with murine feeder cells.
