Human CD3E&CD3G/CD3 epsilon&CD3 gamma Protein
Recombinant Human CD3E&CD3G/CD3 epsilon&CD3 gamma Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp23-Glu120(CD3E)&Gln23-Asn106(CD3G).[Accession | P07766(CD3E)&P09693(CD3G)]
The protein has a predicted MW of 17.9 kDa (CD3E) and 17.9 kDa (CD3G). Due to glycosylation, the protein migrates to 25-40 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Human CD3E&CD3G, His Tag captured on CM5 Chip via Anti-His Antibody can bind OKT3, mFc Tag with an affinity constant of 0.22nM as determined in SPR assay (Biacore T200).
T-cell surface glycoprotein CD3 epsilon & CD3 gamma chain, also known as CD3E & CD3G , 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.
