Two-color flow cytometric analysis of CD40 expression on mouse and rat splenocytes. Mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with PE Rat Anti-Mouse CD5 (Cat. No. 553022/553023) and Alexa Fluor® 647 Hamster Anti-Mouse CD40 (Cat. No. 563638; Left Panel) antibodies. Rat splenic leucocytes were stained with PE Mouse Anti-Rat CD5 (Cat. No. 554851) and Alexa Fluor® 647 Hamster Anti-Mouse CD40 antibodies (Right Panel). The two-color flow cytometric dot plots shows the correlated expression patterns of CD40 versus CD5 for gated events with the forward and side light-scatter characteristics of viable leucocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at http://www.bdbiosciences.com/documents/hamster_chart_11x17.pdf.

The HM40-3 antibody reacts with CD40, a 40-50-kDa glycoprotein expressed on B lymphocytes and other antigen-presenting cells. The CD40 molecule has a central role in B-cell growth and differentiation. Furthermore, interactions of CD40 with its ligand, CD154, are involved in the initiation and effector stages of cell-mediated immune responses. CD40 may be involved in the triggering of NK cells and NK-T cells. Soluble HM40-3 antibody stimulates splenic and peritoneal B cells to proliferate in vitro. This antibody also induces spleen B cells to express the costimulatory molecules CD80 (B7-1) and CD86 (B7-2). HM40-3 mAb has been demonstrated to inhibit the binding of soluble CD154 (gp39, CD40 Ligand) to soluble CD40 and to cell-surface CD40. This hamster mAb to a mouse leukocyte antigen has been observed to cross-react with similar populations of Lewis, Sprague-Dawley, and LOU16 rat leukocytes.
