Background: TRA-1-81

The TRA-1-81 antibody reacts with a high-molecular-mass carbohydrate epitope on the surface of human embryonal carcinoma (EC), embryonic germ (EG), embryonic stem (ES), and induced pluripotent stem (iPS) cells.  TRA-1-81 is an epitope expressed on podocalyxin, also known as Podocalyxin-Like Protein-1 (PCLP1 or PODXL), a type I transmembrane glycoprotein.

• Alternate Names:
