Immunofluorescent analysis of SSEA-1 using anti-SSEA-1 monoclonal antibody (Product# MA1-022) shows specific expression in mouse testicular teratoma F9 cells (shown in green) but not in negative control human NTERA-2 teratocarcinoma cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature. Cells were blocked with 1% Blocker BSA (Product #37525) for 15 minutes at room temperature. Cells were probed with a mouse monoclonal antibody recognizing SSEA-1 (Product# MA1-022), at a dilution of 1:50 for at least 1 hour at room temperature. Cells were washed with PBS and incubated with a fluorescent dye labeled goat-anti-mouse IgM secondary antibody at a dilution of 1:400 for 30 minutes at room temperature. Nuclei (blue) were stained with Hoechst 33342 dye (Product# 62249). Images were taken on a Thermo Scientific ArrayScan at 20X magnification.

SSEA-1 (stage-specific embryonic antigen-1) is a cell surface antigen, expressed in murine embryonic stem cells, embryonal carcinoma cells, and induced pluripotent stem cells (iPS). SSEA-1 is absent in undifferentiated human stem cells but is present on the cell surface after retinoic acid mediated differentiation.
