    Product Information

    Product Description

    This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 647 fluorescent dye under optimal conditions. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated CD3ε (D4V8L) Rabbit mAb #99940.

    Product Usage Information

    Application Dilution
    Immunohistochemistry (Paraffin) 1:50 - 1:200

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Protocol

    Specificity / Sensitivity

    CD3ε (D4V8L) Rabbit mAb (Alexa Fluor® 647 Conjugate) recognizes endogenous levels of total mouse CD3ε protein. Non-specific staining in mouse pancreas has been observed.

    CD3ε (D4V8L) Rabbit mAb (Alexa Fluor® 647 Conjugate) may react weakly with human CD3ε, but is not suggested for use in immunohistochemical analysis of human tissues. Instead, CD3ε (D7A6E) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) #63178 is recommended for IHC analysis of human tissue samples.

    Species Reactivity:

    Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val31 of mouse CD3ε protein.

    Background

    When T cells encounter antigens via the T cell receptor (TCR), information about the quantity and quality of antigens is relayed to the intracellular signal transduction machinery (1). This activation process depends mainly on CD3 (Cluster of Differentiation 3), a multiunit protein complex that directly associates with the TCR. CD3 is composed of four polypeptides: ζ, γ, ε, and δ. Each of these polypeptides contains at least one immunoreceptor tyrosine-based activation motif (ITAM) (2). Engagement of the TCR complex with foreign antigens induces tyrosine phosphorylation in the ITAM motifs and phosphorylated ITAMs function as docking sites for signaling molecules such as ZAP-70 and the p85 subunit of PI-3 kinase (3,4). TCR ligation also induces a conformational change in CD3ε, such that a proline region is exposed and then associates with the adaptor protein Nck (5).
