Regulatory Status Legend
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.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Store undiluted at 4°C.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols.
- 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.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
- 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.
For immunohistochemical staining of mouse tissue, we recommend the use of Purified Rat Anti-Mouse CD40 antibody (Cat. No. 550285, clone 3/23). It is specifically formulated for IHC application.
