Human CD3 epsilon Protein

• Catalog Number: orb348813
• Category: Proteins
• Description: 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.

• Application notes: Human CD3E&CD3G Heterodimer Protein, Fc,His Tag&Fc,Flag Tag is produced by co-expression of CD3E and CD3G, has a calculated MW of 39.2 kDa (CD3E) and 38.6 kDa (CD3G). Subunit CD3E is fused with a human IgG1 Fc tag at the C-terminus, followed by a polyhistidine tag, and subunit CD3G is fused with a human IgG1 Fc tag at the C-terminus, followed by a Flag tag. The predicted N-terminus is Asp 23 (CD3E) & Gln 23 (CD3G). The reducing (R) heterodimer protein migrates as 40-50 kDa due to glycosylation.
• Expiration Date: 6 months from date of receipt.
