Cynomolgus CD3E/CD3 epsilon 1-27 Protein

产品信息(Product Info)

Recombinant Cynomolgus CD3E/CD3 epsilon 1-27 Protein is expressed from HEK293 with hFc tag and Avi tag at the C-Terminus.
It contains Asp22-Thr48 [Accession | Q95LI5.2].

分子量大小(Molecular Weight)

The protein has a predicted MW of 31.3 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Less than 1EU per μg by the LAL method.


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.

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.
