Flow cytometry analysis of SSEA-1 in F9 (red filled histogram) and NCCIT cells (red unfilled histogram) compared to unstained cells (blue histogram). Positive staining is observed on F9 cells when compared to no antibody control (middle panel) and to SSEA-1-negative undifferentiated NCCIT cells (right panel). Cells were fixed with 2% paraformaldehyde and washed with PBS. Cells were blocked with 2% BSA-PBS for 30 minutes at room temperature, and incubated with a PE-conjugated SSEA-1 monoclonal antibody (Product # MA1-022-PE) in 2% BSA-PBS at a dilution of 1:100 for 60 minutes at room temperature. Cells were washed and re-suspended in PBS for FACS analysis.

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.
