Detection of CD3 epsilon in Human Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were stained with Mouse Anti-Human CD3 epsilon Recombinant Monoclonal Antibody (Catalog # MAB100, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody
(Catalog # F0102B).

Immunocytochemistry

CD3 epsilon in Human PBMCs. CD3 epsilon was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Mouse Anti-Human CD3 epsilon Recombinant Monoclonal Antibody (Catalog # MAB100R) at 1.7 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 surfaces. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

T Cell Stimulation

Background: CD3 epsilon

CD3 epsilon is one of at least four invariant proteins that associate with the variable antigen recognition chains of the T cell receptor and function in signal transduction.
