TRA1-81 (TRA-1, Tumor Rejection Antigen 1)

Human embryonal carcinoma (EC) cells are the stem cells of teratocarcinomas, and they are key components of germ cell tumors (GCTs). Embryonal carcinoma, as do all human pluripotent stem cells, expresses TRA-1-60 and TRA-1-81 antigens, and although their molecular identities are unknown, they are commonly used as markers of undifferentiated pluripotent human stem cells.||Applications: |Suitable for use in ELISA, Immunohistochemistry, Flow Cytometry, Western Blot, Immunoprecipitation and Immunofluorescence.
