Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Oct-4 (C52G3) Rabbit mAb detects endogenous levels of total Oct-4 protein.
Source / Purification
Monoclonal antibody is produced by immunizing rabbits with recombinant human Oct-4.
Western Blotting
Western blot analysis of extracts from NCCIT and NTERA2 cells using Oct-4 (C52G3) Rabbit mAb.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded NTERA2 (positive, left) and HeLa (negative, right) cell pellets using Oct-4 (C52G3) Rabbit mAb.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human seminoma, showing nuclear localization, using Oct-4 (C52G3) Rabbit mAb.
Flow Cytometry
Flow cytometric analysis of HeLa cells (blue) and NCCIT cells (green) using Oct-4 (C52G3) Rabbit mAb.
IF-IC
Confocal immunofluorescent analysis of NTERA2 cells using Oct-4 (C52G3) Rabbit mAb (green). Actin filaments have been labeled with DY-554 phalloidin (red).
Background
Oct-4 (POU5F1) is a transcription factor 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. Downregulation of Oct-4 has been shown to trigger cell differentiation (2,3). Oct-4 is a useful germ cell tumor marker (4).
