Biolegend, 653712, Brilliant Violet 421™ anti-Oct4 (Oct3) Antibody, 100μg

Oct4 (Octamer binding transcription factor 4) is an important marker of the undifferentiated state and central regulator of pluripotency in ES cells. When embryonic stem cells are triggered to differentiate, Oct4 is downregulated, thus providing a model for the early events linked to somatic differentiation in the developing embryo. Oct4 is a nuclear protein, with a predicted molecular weight of 39 kD.

RRID: AB_2566690 (BioLegend Cat. No. 653712)
Structure: Belongs to the POU transcription factor family, predicted molecular weight of 39 kD
Distribution: Nuclear protein, expressed in undifferentiated embryonal carcinoma (EC) cells, embryonic stem (ES) cells and embryonic germ (EG) cells
Function: Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Oct4 is a prime candidate for an early developmental control gene. It also is an important marker of the undifferentiated state and central regulator of pluripotency in ES cells.
