Characteristics: 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. Multiparameter Analyses of Oct-2 Expression: Panel 1: Human peripheral blood mononuclear cells, PBMCs, were fixed and permeabilized with BD Pharmingen™ Transcription Factor Buffer Set. Cells were then stained with Purified Rat IgG2a, κ Isotype Control or Purified Rat Anti-Oct-2 and followed with PE Mouse Anti-Rat IgG2a. Prior to fixation, PBMCs were stained with Pacific Blue™ Anti-Human CD3, APC Anti-Human CD19 and FITC Anti-Human CD14. The target event acquisition stop count was 5,000 CD19+ B cells. Two-color flow cytometric data were derived from gated events with the light-scatter characteristics and positive staining for CD3+ T cells (labeled T), CD14+ monocytes (M) or CD19+ B lymphocytes (B). Flow cytometry was performed using a BD LSRFortessa™ Cell Analyzer. Panels 2a, 2b: BALB/c mouse splenocytes and lymph node cells were similarly fixed, permeabilized and stained for Oct-2 as described. After washing, cells were stained with Alexa Fluor® 647 Anti-Mouse CD45R/B220 and FITC Anti-Mouse CD3e and analyzed. Panel 3a: Western blot of Oct-2 expressed by human (Raji, HL-60, or PBMC) or mouse (thymus, spleen) cells. Lysates (20 μg protein/lane) were blotted using Anti-Oct-2, HRP Anti-Rat Ig (Southern Biotech, 3030-05) followed by development with Pierce HRP Substrate (Cat. No. 34080). Oct-2 was identified as a protein band of ~50-60 kDa. Panel 3b: Immunohistochemical analysis of tonsillar Oct-2 expression. Paraffin-embedded tissue sections (5 μm) on poly-l-lysine treated slides were dewaxed, rehydrated and heated (3 min) in TRIS-EDTA 0.01M (pH 9) to retrieve antigen. After cooling, slides were placed in TBS (5 min). Endogenous peroxidase was blocked with a peroxidase-block reagent (DAKO, Denmark). Slides were incubated (30 min, RT) with Anti-Oct-2 antibody. Binding was detected by the peroxidase-based EnVision+ method and sections were stained with hematoxylin.
