Cynomolgus CD3 epsilon, His Tag (CDE-C5226) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Asp 117 (Accession # Q95LI5.2).
Predicted N-terminus: Gln 22
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 11.7 kDa. The protein migrates as 18-20 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>97% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Immobilized Anti Human CD3 MAb, mouse IgG1 (Clone # SP34-2) at 2μg/mL (100 μL/well) can bind Cynomolgus CD3E, His Tag (Catalog # CDE-C5226) with a linear range of 0.4-6.25 ng/mL.
CD3e molecule, epsilon is also known as CD3E, is a T-cell surface single-pass type I membrane glycoprotein. CD3E contains 1 Ig-like (immunoglobulin-like) domain and 1 ITAM domain. CD3E, together with CD3-gamma, CD3-delta and CD3-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. CD3E plays an essential role in T-cell development, and defects in CD3E gene cause severe immunodeficiency. CD3E gene has also been linked to a susceptibility to type I diabetes in women. CD3E has been shown to interact with TOP2B, CD3EAP and NCK2.
