Summary This antibody 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.

Summary The monoclonal antibody 74.5.2 is directed against epitopes in the XC15 peptide that contains a binding site for high-molecular-weight kininogen and Factor XII. Clone 74.5.2 recognizes both the mature (74 – 282) and truncated form, lacking residues 74-95.
