Anti-CD3 epsilon/CD3e Antibody (APC) (Mouse Monoclonal antibody) General Information
Anti-CD3 epsilon/CD3e Antibody (APC)
Reacts with: Human
Human CD3 epsilon/CD3e
Recombinant Human CD3e / CD3 epsilon protein (Catalog#10977-H08H)
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human CD3e / CD3 epsilon (rh CD3e / CD3 epsilon; Catalog#10977-H08H; NP_000724.1; Met1-Asp126) and conjugated with APC under optimum conditions, the unreacted APC was removed.

Flow cytometric analysis of Human CD3 expression on human peripheral blood lymphocytes. Cells were stained with APC-conjugated anti-Human CD3 and PerCP-Cy™5.5 conjugated anti-Human CD19 (BD Pharmingen™ Cat. No. 561295). The dot plots were derived from events with the forward and side light-scatter characteristics of viable lymphocytes.
T-cell surface glycoprotein CD3 epsilon chain, also known as CD3E, is a single-pass type I membrane protein. CD3E contains 1 Ig-like (immunoglobulin-like) domain and 1 ITAM domain. CD3E, together with CD3-gamma, CD3-delta and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. The CD3 epsilon subunit of the T cell receptor (TCR) complex contains two defined signaling domains, a proline-rich sequence and an immune tyrosine activation motifs (ITAMs), and this complex undergoes a conformational change upon ligand binding that is thought to be important for the activation of T cells. In the CD3 epsilon mutant mice, all stages of T cell development and activation that are TCR-dependent were impaired, but not eliminated, including activation of mature naïve T cells with the MHCII presented superantigen, staphylococcal enterotoxin B, or with a strong TCR cross-linking antibody specific for either TCR-Cbeta or CD3 epsilon. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. This complex is critical for T-cell development and function, and represents one of the most complex transmembrane receptors. CD3E plays an essential role in T-cell development, and defects in CD3E gene cause severe immunodeficiency. Homozygous mutations in CD3D and CD3E genes lead to a complete block in T-cell development and thus to an early-onset severe combined immunodeficiency phenotype.
