Anti-SSEA-1 antibodies, human and mouse

Anti-SSEA-1 antibodies, human and mouse

Clone: REA321 | Dilution: 1:50
Clone REA321 recognizes the human and mouse stage specific embryonic antigen 1 (SSEA-1) antigen, which is a Lewis blood group related carbohydrate antigen, also known as CD15. SSEA-1 is expressed on human myelomonocytic cells and is present on neutrophils, eosinophils, and some monocytes, but not on basophils or lymphocytes. The antigen is also expressed on Hodgkin/Reed-Sternberg cells. SSEA-1 is a common surface marker for pluripotency on mouse ES and iPS cells. On human cells in contrast, SSEA-1 is expressed only on early differentiating cells.
Additional information: Clone REA321 displays negligible binding to Fc receptors.

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
