表達區(qū)間及表達系統(tǒng)（Source）

Human PILRA Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Gln20-Ala197.[Accession | Q9UKJ1]

分子量大小（Molecular Weight）

The protein has a predicted MW of 47 kDa. Due to glycosylation, the protein migrates to 60-68 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 and HPLC

制劑（Formulation）

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% 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.
