CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains. These chains associate with the T-cell receptor (TCR) and the CD3-zeta (ζ-chain) to generate an activation signal in T lymphocytes. The TCR, CD3-zeta, and the other CD3 molecules together constitute the TCR complex. The CD3–T cell receptor (TCR) complex plays a central role in the T-cell-mediated immunoresponse as it is involved in the recognition of antigens and subsequent signal transduction and activation of immunocompetent T lymphocytes. Because CD3 is required for T cell activation, drugs (often monoclonal antibodies) that target it are being investigated as immunosuppressant therapies (e.g., otelixizumab, teplizumab) for type 1 diabetes and other autoimmune diseases.
免疫细胞化学
ICC shows positive staining in Jurkat cells. Anti-CD3 epsilon (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
Negative control：ICC shows negative staining in Ramos cells. Anti-CD3 epsilon (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
免疫荧光
IF shows positive staining in paraffin-embedded human spleen. Anti-CD3 epsilon (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
IF shows positive staining in paraffin-embedded human tonsil. Anti-CD3 epsilon (Alexa Fluor® 555 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
