Biotinylated Human CD3 epsilon&CD3 gamma Heterodimer Protein, His, Avitag™&Tag Free (MALS verified)

T-cell surface glycoprotein CD3 delta & CD3 gamma chain, also known as CD3D & CD3G or CD3D&CD3G respectively, are single-pass type I membrane proteins. CD3D, together with CD3- epsilon (CD3E), CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways.

Background

Specifications

Biotinylated Human CD3E&CD3G Heterodimer Protein, His, Avitag&Tag Free is produced by co-expression of CD3E and CD3G, has a calculated MW of 18.6 kDa (CD3E) and 14.7 kDa (CD3G) . Subunit CD3E is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag and subunit CD3G contains no tag at the C-terminus. The reducing (R) heterodimer protein migrates as 20-24 kDa and 25-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker due to glycosylation.
