Alexa Fluor® 647 Rat Anti-Oct-2
Alexa Fluor® 647 Rat Anti-Oct-2

Two-color flow cytometric analysis of Oct-2 expression in human and mouse leucocytes. Human peripheral blood mononuclear cells (PBMCs) and BALB/c mouse splenic leucocytes were fixed and permeabilized with the BD Pharmingen™ Transcription Factor Buffer Set (562574/562725). Cells were then stained with Alexa Fluor® 647 Rat IgG2a, κ Isotype Control (Cat. No. 557906) or Alexa Fluor® 647 Rat Anti-Oct-2 antibody (Cat. No. 563472). Human PBMCs (Left Panels) were counterstained with PE Mouse Anti-Human CD19 antibody (Cat. No. 555413/561741). Mouse splenocytes (Right Panels) were counterstained with Alexa Fluor® 488 Rat Anti-Mouse CD45R/B220 antibody (Cat. No. 557669). The two-color flow cytometric dot plots show the correlated expression of Oct-2 (or Ig Isotype control staining) versus human CD19 (Left Panels) or mouse CD45R/B220 (Right Panels) for gated events with the forward and side light-scatter characteristics of intact lymphoid cells. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer 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® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  4. 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.
  5. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
  6. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  7. 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.

9A2

The 9A2 monoclonal antibody specifically binds to Oct-2 that has a molecular weight of approximately 50-60 kDa. The 9A2 antibody was generated against the 44 N-terminal amino acids common to mouse Oct-2 isoforms and crossreacts with both human and mouse Oct-2. Oct-2 is a POU class 2 homeobox 2 transcription factors (POU2F2) that is also known as OCT2, OTF2, Lymphoid-restricted immunoglobulin octamer-binding protein NF-A2 and Octamer-binding transcription factor 2. The POU domain in the Oct-2 protein is required for low and high affinity cooperative binding of the octomer sequence and heptamer site in immunoglobulin promoters and promoters for other genes. Oct-2 is expressed in B cells, activated CD4+ and CD8+ T cells, monocytes/macrophages and subsets of dendritic cells. Oct-2 is reportedly associated with neoplasms including Diffuse Large B-cell lymphoma and Nodular Lymphocyte predominant Hodgkin's lymphoma. Studies with knockout mouse models suggest Oct-2 is required for B cell maturation, but not for B cell commitment, and for B cell production of IL-6.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
