Source

Biotinylated Cynomolgus CD3E&CD3D/CD3 epsilon&CD3 delta Protein (Primary Amine Labeling) is expressed from HEK293 with hFc tag at the C-terminal. It contains Gln22 - Asp117(CD3E)&Phe22-Ala105(CD3D).

[Accession | Q95LI5.2(CD3E)&Q95LI8(CD3D)]

Molecular Weight

The protein has a predicted MW of 36.9 kDa (CD3E) and 35.4 kDa (CD3D). Due to glycosylation,the protein migrates to 58-62 kDa and 44-46 kDa based on Tris-Bis PAGE result.

Endotoxin

Less than 1EU per μg by the LAL method.

Purity

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

Activity

ELISA Data: Immobilized Anti-CD3, hFc Tag Antibody at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Cynomolgus CD3E&CD3D, hFc Tag with the EC50 of 58.2ng/ml determined by ELISA. 

Formulation

Lyophilized from 0.22μm 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.
