CD3E CD3G Heterodimer Protein, Human, Recombinant

CD3E & CD3G Heterodimer Protein, Human, Recombinant: Product Information

Purity

> 95 % as determined by SDS-PAGE

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method

Activity

Measured by its ability to bind OKT3-mIgG2a in a functional ELISA.

Protein Construction

A DNA sequence encoding the extracellular domain (Met1-Asp126) of human CD3E (NP_000724.1) was fused with the C-terminal FLAG-tagged Fc region of human IgG1 at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the extracellular domain (Met1-Ser116) of human CD3G (NP_000064.1) was fused the Fc region of mouse IgG1 at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the human CD3E/CD3G heterodimer was purified.

Molecule Mass

The recombinant heterodimer of human CD3E/CD3G comprises 681 (353+328) amino acids and has a calculated molecular mass of 76.9 (39.8+37.1) KDa. As a result of glycosylation, the apparent molecular mass of human CD3E/CD3G heterodimer is approximately 42-47 KDa in SDS-PAGE under reducing conditions.
