Total lysates (15 µg protein) from NTERA2 (lane 1), HeLa (lane 2) and NF-1 (lane 3) cells were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:1000 diluted (0.5 µg/mL) Purified anti-Oct4(Oct3) Antibody, clone 3A2A20 (upper), or 1:2000 diluted anti-GAPDH Antibody (lower). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated to HRP for the anti-Oct4 Antibody or 1:3000 diluted Donkey anti-Rabbit-IgG secondary antibody conjugated to HRP for anti-GAPDH Antibody.

    NTERA-2 cells were fixed with 4% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for 5 minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2.5 µg/mL anti-Oct4 (Oct3) (3A2A20) and followed by DyLight™ 594 goat anti-mouse IgG (red) for 1 hour at room temperature. Actin filaments were labeled with Alexa Fluor® 488 Phalloidin (green). Nuclei were counterstained with DAPI (blue). The image was captured with a 40X objective.

Description

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.

Antigen Details

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.
Interaction
SOX2, SOX8, SOX10, androgen receptor, and ETS2
