Human CD3E&CD3D Heterodimer Protein, Llama Fc&Llama Fc, low endotoxin

内毒素:
Less than 0.01 EU per μg by the LAL method.

纯度:
>95% as determined by reduced SDS-PAGE.

活性:
Measured by its binding ability in a functional ELISA. Immobilized Human CD3E&CD3D Heterodimer Protein, Llama Fc&Llama Fc, low endotoxin (Cat. No. CDD-H5258) at 2 μg/mL (100 μL/well) can bind SP34-2 (mouse IgG1) with a linear range of 1-20 ng/mL (Routinely tested).

产品背景:
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.

产品描述:
Human CD3E & CD3D Heterodimer Protein, Llama IgG2b Fc Tag & Llama IgG2b Fc Tag, low endotoxin is produced by co-expression of CD3E and CD3D, has a calculated MW of 42.9 kDa (CD3E) and 40.8 kDa (CD3D). Subunit CD3E is fused with a llama IgG2b Fc tag at the C-terminus and subunit CD3D is fused with a llama IgG2b Fc tag at the C-terminus. The predicted N-terminus is Asp 23 (CD3E) & Phe 22 (CD3D). The reducing (R) protein migrates as 50-60 kDa due to glycosylation.
