CD3 is a primary transmembrane protein found on T cells, with four isoforms namely CD3D, CD3E, CD3G and CD3Z, and its CD3D/CD3E, CD3G/CD3E forms heterodimer forms and the α and β strands of TCR form a TCR-CD3 complex. Antigen-presenting cells (APCs)-presented specific MHC peptide complexes can induce T cell activation with TCR-CD3 complexes.

Source |
Recombinant Human CD3E&CD3G/CD3 epsilon&CD3 gamma Protein is expressed from Expi293 with His tag at the C-terminal. It contains Asp23-Glu120(CD3E)&Gln23-Gln106(CD3G). |
Molecular Weight |
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. |
Purity |
> 95% as determined by SDS-PAGE and HPLC |
Endotoxin |
< 1.0 EU per 1μg of the protein by the LAL method. |
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended. Dissolve the lyophilized protein in distilled water. |
运输与保存方法
The products are shipped with ice pack and can be stored at -25~-15℃ for 1 year.
2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
