Product Information
Product Description
This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 488 fluorescent dye under optimal conditions. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated CD3ε (D7A6E™) XP® Rabbit mAb #85061.
Product Usage Information
| Application | Dilution |
|---|---|
| Immunohistochemistry (Paraffin) | 1:100 - 1:400 |
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 (D7A6E™) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total CD3ε protein. This antibody recognizes human CD3ε protein and is also reactive with mouse CD3ε; however, this antibody is not suggested for immunohistochemical analysis of mouse tissues.
Species Reactivity:
Human, Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu178 of human 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).
