Multicolor flow cytometric analysis of Pax-5 expression in human and mouse leucocytes. Human peripheral blood mononuclear cells (PBMC) and BALB/c mouse splenic leucocytes were fixed and permeabilized using the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725). The cells were then stained with either Alexa Fluor® 488 Rat Anti-Mouse Pax-5 antibody (Cat. No. 562816) or Alexa Fluor® 488 Rat IgG2a, κ Isotype Control (Cat. No. 557676). The PBMC were counterstained with APC Mouse Anti-Human CD21 antibody (Cat. No. 561767/561357/559867). The mouse splenic leucocytes were counterstained with APC Rat Anti-Mouse CD45R/B220 antibody (Cat. No. 553092/561880). Flow cytometric analysis was performed using a BD LSR™ II Flow Cytometer System. Panel A. Human Peripheral Blood Lymphocytes: The two-color flow cytometric dot plots show the correlated expression patterns of Ig Isotype control staining (Left Plot) and Pax-5 (Right Plot) versus CD21 for events with the forward and side light-scatter characteristics of intact human peripheral blood lymphocytes. Panel B. Mouse Splenocytes: The dot plots show the coexpression patterns of Ig Isotype control staining (Left Plot) or Pax-5 (Right Plot) versus CD45R/B220 for events with the light-scatter characteristics of intact mouse splenocytes.

The 1H9 monoclonal antibody clone specifically binds to human and mouse Paired box protein Pax-5. Pax-5 is a ~50 kDa protein that is also known as B-cell-specific transcription factor and B cell specific activator protein (BSAP). Pax-5 is a member of the paired box (Pax) family of transcription factors. It is expressed in pro-B, pre-B and mature B cells. Through the Groucho family of co-repressors, Pax-5 likely functions as a transcriptional repressor of non-B-lymphoid genes during the B cell commitment process. In the early stages of B cell development, Pax-5 influences the expression of several B-cell-specific genes, such as CD19 and CD20 and maintains B cell identity. Pax-5 suppression is involved in the upregulation of Blimp-1 leading to the development of Pax-5-negative plasma cells. Pax-5 mRNA is transiently detected in the mesencephalon and spinal cord during embryogenesis. Expression then shifts to the fetal liver and correlates with the onset of B lymphopoiesis. Altered forms and expression patterns of Pax-5 have been associated with some lymphoid and nonlymphoid cancers.
