mouse monoclonal IgG3; SSEA-4 Antibody (813-70) is an IgG3 κ mouse monoclonal SSEA-4 antibody (also designated Stem cell marker SSEA4 antibody, glycosphingolipid epitope specific antibody, or pluripotent surface marker SSEA4 antibody) that detects the SSEA-4 protein of mouse, rat and human origin by IF and FCM. SSEA-4 Antibody (813-70) is available as both the non-conjugated anti-SSEA-4 antibody form, as well as multiple conjugated forms of anti-SSEA-4 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Embryonic stem cells have the ability to remain undifferentiated and proliferate indefinitely in vitro, while maintaining the potential to differentiate into derivatives of all three embryonic germ layers. Undifferentiated human embryonal carcinoma (EC) cells are the stem cells of teratocarcinomas and are characterized by the expression of Stage Specific Embryonic Antigens SSEA-1 and SSEA-3, TRA-2-39, TRA-2-54 and the high molecular weight glycoproteins TRA-1-60 and TRA-1-81. In addition, SSEA-1, SSEA-3 and SSEA-4 are markers that characterize embryonic stem (ES) and embryonic germ (EG) cells. Specifically, undifferentiated cells from the human ES cell line H7 express SSEA-3, SSEA-4, TRA-1-60 and TRA-1-81, but not SSEA-1. Interferon induces expression of SSEA-3 and SSEA-4 in EC cells without inhibiting their growth or inducing their differentiation.
