Oct-3/4 Antibody [Unconjugated]

Simple Western lane view shows lysates of BG01V human embryonic stem cells and NTera‑2 human testicular embryonic carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Oct‑3/4 at approximately 50 kDa (as indicated) using 20 µg/mL of Goat Anti-Human/Mouse Oct‑3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Western blot shows lysates of BG01V human embryonic stem cells and D3 mouse embryonic stem cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse Oct‑3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Oct‑3/4 at approximately 48 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

BG01V human embryonic stem cells were fixed using formaldehyde, resuspended in lysis buffer, and sonicated to shear chromatin. Oct‑3/4/DNA complexes were immunoprecipitated using 5 μg Goat Anti-Human/Mouse Oct‑3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759) or control antibody (Catalog # AB-108-C) for 15 minutes in an ultrasonic bath, followed by Biotinylated Anti-Goat IgG Secondary Antibody (Catalog # BAF109). Immunocomplexes were captured using 50 μL of MagCellect Streptavidin Ferrofluid (Catalog # MAG999) and DNA was purified using chelating resin solution. The nanog promoter was detected by standard PCR.

Alkaline phosphatase (ALPL) and Oct‑3/4 were detected in human BG01V embryonic stem cells using 10 µg/mL Human/Mouse/Rat ALPL Monoclonal Antibody (Catalog # MAB1448) and 10 µg/mL Goat Anti-Human/Mouse Oct‑3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759). Cells were incubated with primary antibodies for 3 hours at room temperature. Cells were stained for ALPL using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (pseudo-stained green; Catalog # NL007), and stained for Oct-3/4 using the NorthernLights 637-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL002).

Background

Oct-3/4, a member of POU transcription factors, was identified as a DNA-binding protein that activates gene transcription via a cis-element containing an octamer motif (1). It is expressed in totipotent embryonic stem and germ cells (2, 3). A critical amount of Oct-3/4 expressed is required to sustain stem cell self-renewal and pluripotency (4). When embryonic stem cells are induced to differentiate, Oct-3/4 is downregulated and this downregulation of Oct-3/4 has proven to be essential for proper and divergent developmental program (5). The Oct-3/4 molecule is not only a master regulator of pluripotency that controls the lineage commitment but also is the most recognized marker used for the identification of totipotent embryonic stem cells.
