蛋白结构(Molecular Characterization)

Online(Asp 23 - Asp 126) NP_000724.1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 12.6 kDa. The protein migrates as 15-16 kDa under reducing (R) condition (SDS-PAGE).

标记(Biotinylation)

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 2-3 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by reduced SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Background

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.
