Product details
References
Isotype
Mouse IgG1
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.
Application
IP, WB, FC (QC tested), IHC(F), ICC
Reactivity
Mouse, Human
Immunogen
Purified human CD3 proteins isolated from thymus
Other names
CD3 epsilon chain, T3E, CD3epsilon, IMD18
Preparation
Purified by protein-A affinity chromatography
Formulation
Phosphate buffered saline (PBS) solution with 15 mM sodium azide
