Rex‑1 in BG01V Human Stem Cells. Rex‑1 was detected in immersion fixed BG01V human embryonic stem cells using 10 µg/mL Human Rex‑1 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF3598) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Streptavidin (red; Catalog # NL999) and counterstained with DAPI (blue).

Rex-1 is a zinc finger family transcription factor that is highly expressed in embryonic stem cells. It is one of several gene markers used to identify undifferentiated stem cells, and its expression is downregulated upon stem cell differentiation. Human Rex-1 is 310 amino acids (aa) in length.
