Recombinant Human IL-13Ra1 Protein,His Tag

表达区间及表达系统（Source）

Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Ala27-Thr343.[Uniprot | P78552-1]

分子量大小

（Molecular Weight）

The protein has a predicted MW of 37.7 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.

内毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

纯度（Purity）

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

活性（Activity）

SPR Data: Human IL-13, His Tag immobilized on CM5 Chip can bind Human IL-13Ra1, His Tag with an affinity constant of 1μM as determined in a SPR assay

制剂（Formulation）

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法（Reconstitution）

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