Detection of Human Oct-3/4 by Western Blot.|
Western blot shows lysates of BG01V human embryonic stem cells and NTera‑2 human testicular embryonic carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Rat Anti-Human/Mouse Oct‑3/4 Monoclonal Antibody (Catalog # MAB1759) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Oct-3/4 at approximately 46 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Oct‑3/4 in BG01V Human Embryonic Stem Cells. |
Oct‑3/4 was detected in immersion fixed BG01V human embryonic stem cells using Rat Anti-Human/Mouse Oct‑3/4 Monoclonal Antibody (Catalog # MAB1759) at 10 µg/mL for 3 hours at room temperature. Cells were stained using Rhodamine Red-coupled anti-rat IgG (red) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Oct-3/4, also termed Oct-3 or Oct-4, is a POU transcription factor that is expressed in totipotent embryonic stem and germ cells.(2, 3) Oct-3/4 is required to sustain stem cell self-renewal and pluripotency.(4) It is considered a master regulator of pluripotency that controls lineage commitment and is the most widely recognized marker of totipotent embryonic stem cells.
