Human CD3 epsilon&CD3 delta Heterodimer Protein, Fc Tag&Fc Tag (MALS verified)

T-cell surface glycoprotein CD3 delta & CD3 epsilon chain, also known as CD3D & CD3E or CD3D&CD3E 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

Human CD3E&CD3D Heterodimer Protein, Fc Tag&Fc Tag is produced by co-expression of CD3E and CD3D, has a calculated MW of 38.3 kDa (CD3E) and 35.8 kDa (CD3D) . Subunit CD3E is fused with a human IgG1 Fc tag at the C-terminus and subunit CD3D is fused with a human IgG1 Fc tag at the C-terminus. As a result of glycosylation, the protein migrates as 45-60 kDa under reducing (R) condition, and 90-110 kDa under non-reducing (NR) condition (SDS-PAGE) .
