Detection of CD3 in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes were stained with either Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB8481R, filled histogram) or Rat IgG2B Isotype Control (Catalog # MAB006, open histogram) followed by PE-conjugated anti-Rat IgG Secondary Antibody (Catalog # F0105B).

CD3 in Mouse Splenocytes. CD3 was detected in immersion fixed mouse splenocytes using Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB4841R) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell membrane. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

CD3 in Mouse Spleen Tissue. CD3 was detected in immersion fixed paraffin-embedded sections of mouse spleen tissue using Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB4841R) at 15 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC005). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell membrane in lymphocytes.

Background: CD3

Monoclonal 17A2 was generated by immunizing rats with a T-cell hybridoma (1). This antibody has been shown to react with the epsilon chain of the CD3 complex (1). The CD3 protein complex is expressed on thymocytes and mature T-cells and, therefore, is a useful reagent to monitor T-cell frequencies in tissues.
