Monoclonal antibody R-10G recognizes keratan sulfate lacking oversulfated structures in oligosaccharide segments of keratan sulfate glycosaminoglycan chains on human induced pluripotent stem (hiPS) cells. Digestion with Keratanase II, Keratanase or Endo-beta-galactosidase removes these epitopes from keratan sulfate proteoglycans. Unlike commercially available keratan sulfate-recognizing antibodies 5D4 and BCD4, R-10G recognizes keratan sulfate with a low degree of sulfation. The antigenic polypeptide portion has been identified as podocalyxin. Importantly, R-10G antibody binds to human iPS cells and human ES cells, but only at very low levels to human embryonal carcinoma (EC) cells. Unlike widely used human pluripotent stem cell marker antibodies TRA-1-60 (IgM) and TRA-1-81 (IgM), R-10G (IgG1) binds only weakly to EC cells. Therefore, R-10G is useful for quality control of human iPS and ES cells.
