PE Mouse anti-Oct3/4
PE Mouse anti-Oct3/4

Analysis of Oct3/4 in human embryonal carcinoma cells.  NCCIT cells (ATCC CRL-2073) were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, permeabilized with BD™ Phosflow Perm Buffer III (Cat. No. 558050) on ice for 30 minutes, and then stained with either PE Mouse anti-Oct3/4 (shaded histogram) or PE Mouse IgG1, κ Isotype Control (open histogram).  Flow cytometry was performed on a BD™ LSR II flow cytometry system.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

40/Oct-3

Development of a multicellular organism from a single fertilized cell is regulated by the coordinated activity of DNA transcription factors.  Oct3/4, a member of the POU family of transcription factors, functions in pluripotent cells of early embryonic stem cell (ES) lines and embryonal carcinomas (EC).  Other members of the POU family include Oct1, Oct2, Pit-1, and unc-86.  The POU domain, a 150-amino acid region that determines binding specificity, is conserved among these proteins and consists of 3 subdomains: POU-specific A and B subdomains and a homeobox-like subdomain.  Oct3/4 is expressed in undifferentiated cells, but is lost as cells are induced to differentiate.  Oct3/4 is not expressed in adult tissues.  The interaction of Oct3/4 with SOX2, another embryonic transcription factor, produces an active complex that regulates expression of genes such as Nanog, UTF1, and FGF4.  Although Oct3/4 is specifically phosphorylated on serine residues, this modification is not required for DNA binding, but may affect its transactivation potential.  Thus, Oct3/4 is a transcription factor that plays an important role in determining early steps of embryogenesis and differentiation.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
