The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. [RefSeq]

Optimal dilution of the CD3 epsilon antibody should be determined by the researcher.

A synthetic peptide specific to human CD3 epsilon / CD3E was used as the immunogen for the CD3 epsilon antibody.

Store the CD3 epsilon antibody at -20oC.
