Flow cytometric analysis of CD3 expression in rat spleen and thymus. LEW splenocytes were simultaneously stained with FITC Mouse Anti-Rat CD4 (Cat. No. 554837; left panels), FITC Mouse Anti-Rat CD8a (Cat. No. 554856; left panels) and PE Mouse Anti-Rat CD3 (Cat. No. 554833; bottom panels) monoclonal antibodies. Please note that CD3- CD4+ monocytes and CD3- CD8a+ NK cells may be found in the rat spleen. LEW thymocytes were stained with PE Mouse Anti-Rat CD3 (bottom right panel) or unstained (top right panel). The fluorescence contour plots/histograms were derived from gated events with the forward and side light-scattering characteristics of viable cells. Flow cytometry was performed on a BD FACScan™.

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.

The G4.18 monoclonal antibody specifically recognizes the T-cell receptor-associated CD3 cell-surface antigen found on thymocytes, peripheral T lymphocytes, and dendritic epidermal T cells. It has been reported that CD3 expression is down-regulated within 24 hours in concanavalin A-stimulated rat T cells, and soluble mAb inhibits the allogeneic mixed-lymphocyte proliferative response and cell-mediated cytotoxicity to allogeneic target cells. In vivo treatment with G4.18 mAb prevents cardiac and skin allograft rejection, resulting in donor-specific tolerance. Pre-incubation of splenocytes with the alternate anti-rat CD3 monoclonal antibody, 1F4, blocks staining with mAb G4.18.
