This antibody recognizes the stage-specific embryonic antigen-3 (SSEA-3) that is expressed upon the surface of human teratocarcinoma stem (EC), embryonic germ (EG), embryonic stem (ES), and induced pluripotent stem (iPS) cells. No immunoreactivity is evident with undifferentiated murine EC, ES and EG cells. Expression of SSEA-3 is down regulated following differentiation of human EC cells. In contrast, the differentiation of murine EC and ES/iPS cells may be accompanied by an increase in SSEA-3 expression.

Sample Data

Figure A: FC analysis on H1 human ES cells at a 1:100 dilution.Red histogram represents SSEA-3 Antibody and open histogram represents isotype control. A PE-conjugated anti-Rat IgM was used as the secondary antibody. Figure B: ICC analysis on H1 human ES cells. Cells were stained with SSEA-3 Antibody at a 1:100 dilution followed by an Alexa 488-conjugated secondary antibody (green). Nuclei were counterstained with DAPI (blue).
