Recombinant Biotinylated Cynomolgus IL-2R beta/CD122 Protein (Primary Amine Labeling) ,His Tag

表达区间及表达系统（Source）

Biotinylated Cynomolgus IL-2 R beta/CD122 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-terminal.

It contains Ala27-Asp239.[Accession | Q38J85]

分子量大小（Molecular Weight）

The protein has a predicted MW of 25.6 kDa. Due to glycosylation, the protein migrates to 40-50 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
> 90% as determined by HPLC

           活性（Activity）

SPR Data: Biotinylated Cynomolgus IL-2 R beta, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-2, No Tag with an affinity constant of 0.148 μM as determined in 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.
