Scientific Data Images for OCT4 Antibody - BSA Free

Western Blot: OCT4 AntibodyBSA Free [NB100-2379]

Western Blot: OCT4 Antibody [NB100-2379] - YM155 significantly reduced tumorsphere formation and inhibited EGFR autophosphorylation and G9a expression. YM155 is reported to suppress cancer stemness; therefore, we used this compound to investigate the cellular mechanism of tumorsphere formation. To compare the cytotoxic capacity of YM155 against tumorsphere formation and parental cell lines, YM155 was applied to HCC827 and A549 cells in the stemness cultured or integrated medium. (F) Moreover, YM155 inhibited EGFR autophosphorylation in A549-derived tumorspheres and reduced Oct4 expression.

Flow Cytometry: OCT4 Antibody [NB100-2379] - An intracellular stain was performed on Jurkat with NB100-2379 and a matched isotype control. Cells were fixed with 4% PFA and then permeablized with 0.1% saponin. Cells were incubated in an antibody dilution of 1 ug/mL for 30 minutes at room temperature, followed by Rabbit IgG (H+L) Cross-Adsorbed Secondary Antibody.

Background: OCT4

OCT4 (octamer-binding protein 4) is a transcription factor that binds to the octamer motif (5'-ATTTGCAT-3') and generates a trimeric complex with SOX2 on DNA for controlling the expression of several genes (YES1, FGF4, UTF1, ZFP206 etc.) involved in embryonic development. Expressed mainly in the nucleus, OCT4 interacts with UBE2I, ZSCAN10, PKM, WWP2 etc. and OCT4-PKM interaction positively regulate OCT4's transcriptional activity. Once translated, its modifications such as sumoylation enhances the protein stability, DNA binding and transactivation activity and is required for enhanced YES1 expression. OCT4 undergoes 'Lys-63'-linked polyubiquitination by WWP2 leading to proteasomal degradation. OCT4 is found in oocytes and is zygotically expressed in pluripotent cells of pre-gastrulation embryos, and has been observed to be essential for early embryogenesis as well as for embryonic stem cell pluripotency. OCT4 is expressed in developing brain with highest levels in specific cell layers of the cortex, the olfactory bulb, hippocampus and cerebellum. Its expression decreases gradually after embryoid body formation, however, improper re-activation of OCT4 contributes to oncogenic processes and it has been implicated in certain malignancies such as breast and ovarian cancer.
