Background

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.

Specifications

Alexa Fluor 488-Labeled Human CD3E&CD3D Heterodimer Protein, His Tag&Tag Free, produced by co-expression of CD3E and CD3D. Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3D contains no tag.
