Human CD3 epsilon Protein, His Tag (MALS verified)

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.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 16.9 kDa. Maybe caused by unknown PTMs, the protein migrates as 18-19 kDa and 21-22 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition, and 35-43 kDa under non-reducing (NR) condition (SDS-PAGE) .

● -20°C to -70°C for 24 months in lyophilized state; ● -70°C for 12 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human CD3 epsilon, His Tag (Cat. No. CDE-H5223) at 1 μg/mL (100 μL/well) can bind Mouse Anti-Human CD3 (SP34-2) with a linear range of 0.2-3 ng/mL (QC tested).
