Protocols
- 2788:
- Western Blotting
Specificity / Sensitivity
Oct-4 (V241) Antibody detects endogenous levels of total Oct-4 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids surrounding Val241 of human Oct-4. Antibodies are purified by peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from NCCIT and F9 cells using Oct-4 (V241) Antibody.
Background
Oct-4 (POU5F1) is a transcription factor highly expressed in undifferentiated embryonic stem cells and embryonic germ cells (1). A network of key factors that includes Oct-4, Nanog, and Sox2 is necessary for the maintenance of pluripotent potential, and downregulation of Oct-4 has been shown to trigger cell differentiation (2,3). Oct-4 is a useful germ cell tumor marker (4). Oct-4 exists as two splice variants, Oct-4A and Oct-4B (5). Recent studies have suggested that it is the Oct-4A isoform that has the ability to confer and sustain pluripotency and that Oct-4B may exist in some somatic, non-pluripotent cells (6,7).
