      Alexa Fluor® 488 Mouse anti-Oct3/4
      Alexa Fluor® 488 Mouse anti-Oct3/4
      Flow cytometric analysis of Alexa Fluor® 488 anti Oct3/4 in H9 cells.  H9 human embryonic stem (ES) cells (WiCell, Madison, WI) 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 Alexa Fluor® 488 Mouse anti-Oct3/4 (Cat. No. 560253; solid line histogram) or Alexa Fluor® 488 Mouse IgG1, κ Isotype Control (Cat. No. 565572, dashed line histogram).  Flow cytometry was performed on a BD FACSCanto™ II flow cytometry system.

      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 to Alexa Fluor® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.

      Recommended Assay Procedures

      BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells.   However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls.  It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.

      Product Notices

      1. 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).
      2. An isotype control should be used at the same concentration as the antibody of interest.
      3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      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. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
      6. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
      7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

      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.

      Alexa Fluor™ 488
      Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
