Application

Clone APA1/1 has been demonstrated to recognize a site on CD3&epsilon: that is exposed upon engagement of the T-Cell Receptor complex. Exposure of this neoepitope precedes CD3 phosphorylation and recruitment and activation of ZAP-70, which initiates the signaling cascade produced by T-cell activation. As such, clone APA1/1 provides the earliest known marker for T-Cell Receptor engagement, and thus T-cell activation.
Detect CD3ε using this Anti-CD3ε Antibody, clone APA1/1 validated for use in FC, IP, WB & IC.

Diana Gil et al.
Cell, 109(7), 901-912 (2002-07-12)
How membrane receptors initiate signal transduction upon ligand binding is a matter of intense scrutiny. The T cell receptor complex (TCR-CD3) is composed of TCR alpha/beta ligand binding subunits bound to the CD3 subunits responsible for signal transduction. Although it

The size and sensitivity of the T-cell repertoire governs the effectiveness of immune responses against invading pathogens. Both are modulated by T-cell receptor (TCR) activity through molecular mechanisms, which remain unclear. Here, we provide genetic evidence that the SH2/SH3 domain
B Alarcón et al.
The EMBO journal, 10(4), 903-912 (1991-04-01)
The T cell receptor for antigen (TCR) consists of two glycoproteins containing variable regions (TCR-alpha/beta or TCR-gamma/delta) which are expressed on the cell surface in association with at least four invariant proteins (CD3-gamma, -delta, -epsilon and -zeta). CD3-gamma and CD3-delta
A Borroto et al.
The Journal of biological chemistry, 273(21), 12807-12816 (1998-05-28)
Assembly of the six-chain T cell antigen receptor-CD3 complex takes place by pairwise interactions. Thus, CD3-epsilon interacts with either CD3-gamma or CD3-delta, and these dimers then associate with the TCR heterodimer (alpha.beta or gamma.delta) and the CD3-zeta homodimer to constitute

Leukemia, 30(1), 74-85 (2015-07-30)
The degree of chronic lymphocytic leukemia (CLL) B-cell antigen receptor (BCR) binding to myosin-exposed apoptotic cells (MEACs) correlates with worse patient outcomes, suggesting a link to disease activity. Therefore, we studied MEAC formation and the effects of MEAC binding on
