    Protocol

    Specificity / Sensitivity

    Oct-4A (C30A3) Rabbit Monoclonal Antibody detects endogenous levels of total Oct-4A protein. Based on high sequence homology, this antibody may also detect OCT4-PG1.

    Species Reactivity:

    Human, Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human Oct-4A. The epitope has been mapped to residues surrounding Gly52.

    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). Research studies have demonstrated that 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 the Oct-4A isoform has the ability to confer and sustain pluripotency, while Oct-4B may exist in some somatic, non-pluripotent cells (6,7).
