Western Blotting

Western blot analysis of NCCIT and NTERA2 cell extracts using Oct-4 Antibody.
IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human seminoma (left) or normal testis (right), showing nuclear localization using Oct-4 Antibody.
Flow Cytometry

Flow cytometric analysis of untreated NCCIT cells using Oct-4 Antibody (blue) compared to a nonspecific negative control antibody (red).
IF-IC

Confocal immunofluorescent analysis of NCCIT cells using Oct-4 Antibody (green) and β-Tubulin (9F3) Rabbit mAb (Alexa Fluor® 555 Conjugate) #2116 (red).
Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 NCCIT cells and either 20 μl of Oct-4 Antibody #2750 or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human Oct-4 Promoter Primers #4641, SimpleChIP® Human Sox2 Promoter Primers #4649, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
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).
