Biotinylated Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein

Recombinant Biotinylated Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein is expressed from HEK293 with hFc tag and Avi tag at the C-Terminus.It contains Asp23-Asp126(CD3E) & Phe22-Ala105(CD3D). T-cell surface glycoprotein CD3 epsilon&CD3 delta chain, also known as CD3E&CD3D , are single-pass type I membrane proteins.When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain.
