      BV421 Mouse Anti-Oct3/4
      BV421 Mouse Anti-Oct3/4
      Flow cytometric analysis and immunofluorescent staining of Oct3/4 expression in human embryonic stem (ES) cells. LEFT: H9 human ES cells (WiCell, Madison, WI) grown in mTESR™1 media (StemCell Technologies) were harvested using Accutase™ Cell Detachment Solution (Cat. No. 561527), fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), and permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050). Cells were stained with either BD Horizon™ BV421 Mouse anti-Oct3/4 (Cat. No. 565644, solid line) or BD Horizon™ BV421 Mouse IgG1, κ Isotype Control (Cat. No. 562438, dashed line) at matched concentrations. Histograms were derived from gated events based on light scattering characteristics of human ES cells. Flow cytometry was performed on a BD LSRFortessa™ Flow Cytometry System. RIGHT: H9 human ES cells (WiCell, Madison, WI) were cultured in a 96-well imaging plate, fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050), and blocked with 5% goat serum, 1% BSA, and 0.5% Triton™ X-100 diluted in 1× PBS. Cells were stained with BD Horizon™ BV421 Mouse Anti-Human Oct3/4 antibody (Cat. No. 565644, pseudo-colored red) and counterstained with BD Pharmingen™ DRAQ5™ (Cat. No. 564903, pseudo-colored blue). Images were captured on a standard epifluorescence microscope. Original magnification, 20×.

      Preparation And Storage

      Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

      Recommended Assay Procedures

      For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

      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.

      BV421
      The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
