Cynomolgus CD3E/CD3 epsilon Protein

Product Info

Recombinant Cynomolgus CD3E/CD3 Epsilon Protein is expressed from Expi293 with His tag at the C-terminal. It contains Gln22-Asp117.[Accession | Q95LI5-1]

Molecular Weight

The protein has a predicted MW of 11.7 kDa. Due to glycosylation, the protein migrates to 14-16 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 SEC-HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


The product should be stored at -70℃ or -20℃.

CD3E, is a single-pass type I membrane protein.CD3 (cluster of differentiation 3) T cell co-receptor helps to activate both the cytotoxic T cell (CD8 naive T cells) and also T helper cells (CD4 naive T cells). It consists of a protein complex and is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains.
