Data Examples
CD3 in Mouse Brain. CD3 was detected in perfusion fixed HSV-1 infected frozen sections of mouse brain (perivascular cuffing) using 10 µg/mL Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB4841) overnight at 4 °C. Tissue was stained (green) and counterstained with DAPI (blue). View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.
CD3 in Mouse Splenocytes. CD3 was detected in immersion fixed mouse splenocytes using Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB4841) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (yellow; Catalog # NL007) and counterstained with DAPI (blue).

Background: CD3
The T cell receptor (TCR)/CD3 complex consists of two variable antigen-recognition receptor chains (TCR-alpha/TCR-beta or TCR-gamma/TCR-delta) that are non-covalently linked to at least four different invariant chains: CD3 gamma, CD3 delta, CD3 epsilon, and the CD3 zeta chain that exists as either a homodimer or as a heterodimer with its splice-variant the CD3 eta chain. The CD3 complex functions to transduce intracellular signals during TCR antigen recognition. CD3 is expressed early in thymocyte development, and on a subset of NK cells. CD3 epsilon is one of at least three invariant proteins that associate with the variable antigen recognition chains of the T cell receptor and function in signal transduction.
