表達區間及表達系統（Source）

Recombinant Biotinylated Human LILRB2/CD85d/ILT4 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Gln22-His458.[Accession | Q8N423-1]

分子量大小（Molecular Weight）

The protein has a predicted MW of 50.2 kDa. Due to glycosylation, the protein migrates to 70-75 kDa based on Tris-Bis PAGE result.

內毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

純度（Purity）

> 95% as determined by Tris-Bis PAGE

> 95% as determined by HPLC

  活性（Activity）

ELISA Data:Immobilized Anti-LILRB2 Antibody, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human LILRB2, His Tag with the EC50 of 72.6ng/ml determined by ELISA.

制劑（Formulation）

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

重構方法（Reconstitution）

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