Anti-OCT4 Antibody

This Antibodies.com rabbit polyclonal antibody targets OCT4 (POU domain class 5 transcription factor 1, also known as POU5F1), a homeodomain transcription factor of approximately 38-45 kDa that plays a central role in maintaining pluripotency and self-renewal of embryonic stem cells and induced pluripotent stem cells. Supplied as 100 µg of liquid IgG in a single vial, the unconjugated reagent is validated for western blot detection in human and mouse samples, including cell lysates from pluripotent stem cell cultures used in reprogramming and differentiation studies. For optimal stability, aliquot upon receipt and store at -20 °C, avoiding repeated freeze-thaw cycles to preserve antibody activity. Intended for research use only, the antibody is widely referenced in pluripotency characterization workflows where POU5F1 expression serves as a canonical marker of the undifferentiated state.
