Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),
Specificity / Sensitivity
Oct-4 (D7O5Z) Mouse mAb recognizes endogenous levels of total Oct-4 protein. This antibody does not perform optimally on mouse cells in immunofluorescence assays.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Phe38 of human Oct-4 protein.
Confocal immunofluorescent analysis of NTERA-2 (left) and HeLa (right) cells using Oct-4 (D7O5Z) Mouse mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). As expected, HeLa cells are negative for Oct-4 expression.
Western blot analysis of extracts from NTERA-2 and HeLa cells using Oct-4 (D7O5Z) Mouse mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). As expected, HeLa cells are negative for Oct-4 expression.
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).
