Sox2, also known as SRY (sex determining region Y)-box 2, is a transcription factor essential for maintaining self-renewal of undifferentiated embryonic stem (ES) cells. Chromatin immunoprecipitation experiments have shown that Sox2 and Oct4 bind to thousands of gene regulatory sites, highlighting the importance of these transcription factors in early embryonic development. The knockdown of Sox2gene expression by siRNA in human ES cells results in loss of the undifferentiated stem cell state. Sox2 is one of the key transcription factors used to reprogram mouse and human fibroblasts to a pluripotent state. The Sox2 Antibody (Affinity Purified) was screened on human and mouse ES cells using immunocytochemistry and flow cytometry and selected as the best antibody available for researchers needing to demonstrate pluripotency.

Immunocytochemistry analysis of Sox2 on R1 mouse ES cells. Cells were stained with Sox2 Antibody (Affinity Purified) using a 1:100 dilution followed by a secondary Cy3 conjugated antibody (red). DAPI staining was performed to visualize nuclei (blue).
