CD3E & CD3D,CD3 delta & CD3 epsilon,CD3 delta / epsilon
Cynomolgus CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag (CDD-C52W4) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Asp 117 (CD3E) & Phe 22 - Ala 105 (CD3D) (Accession # Q95LI5 (CD3E) & Q95LI8 (CD3D)).
Predicted N-terminus: Gln 22 (CD3E) & Phe 22 (CD3D)
Cynomolgus CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag is produced by co-expression of CD3E and CD3D, has a calculated MW of 15.5 kDa (CD3E) and 14.5 kDa (CD3D). Subunit CD3E is fused with his tag at the C-terminus and subunit CD3D is fused with flag tag at the C-terminus. The predicted N-terminus is Gln 22 (CD3E) and Phe 22 (CD3D). The reducing (R) heterodimer protein migrates as 19-22 kDa and 25-40 kDa due to glyosylation.
Less than 1.0 EU per μg by the LAL method.
>92% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Immobilized Mouse Anti-Human CD3 (SP34-2) at 1 μg/mL (100 μL/well) can bind Cynomolgus CD3E&CD3D Heterodimer Protein, His Tag&Flag Tag (Cat. No. CDD-C52W4) with a linear range of 0.2-5 ng/mL (QC tested).
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.
