Quick Overview for CD3 epsilon antibody (Activation Site) (PE) (ABIN457363)

Target: CD3 epsilon (CD3E)

Reactivity: Human, Mouse

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD3 epsilon antibody is conjugated to PE

Application: Intracellular Flow Cytometry (ICFC)

Clone: APA1-1

Product Details anti-CD3 epsilon Antibody (PE)

Binding Specificity: Activation Site

Purpose: Anti-CD3 epsilon (activation epitope) PE

Specificity: The mouse monoclonal antibody APA1/1 recognizes an activation-dependent intracellular epitope of CD3 epsilon. Exposure of the epitope precedes CD3 phosphorylation and recruitment and activation of ZAP70, which initiates the signaling cascade produced by T-cell activation. APA1/1 provides the earliest known marker for TCR-mediated T cell activation.

Cross-Reactivity (Details): Human, Mouse

Purification: Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Immunogen: Purified human CD3 proteins isolated from thymus

Isotype: IgG1

Target Details for CD3 epsilon

Target: CD3 epsilon (CD3E)

Alternative Name: CD3 epsilon

Background: CD3 antigen, epsilon polypeptide,CD3 complex is crucial in transducing antigen-recognition signals into the cytoplasm of T cells and in regulating the cell surface expression of the TCR complex. T cell activation through the antigen receptor (TCR) involves the cytoplasmic tails of the CD3 subunits CD3 gamma, CD3 delta, CD3 epsilon and CD3 zeta. These CD3 subunits are structurally related members of the immunoglobulins super family encoded by closely linked genes on human chromosome 11. The CD3 components have long cytoplasmic tails that associate with cytoplasmic signal transduction molecules. This association is mediated at least in part by a double tyrosine-based motif present in a single copy in the CD3 subunits. CD3 may play a role in TCR-induced growth arrest, cell survival and proliferation.,CD3 epsilon chain, T3E, IMD18
