分子别名（Synonyms）

GFR alpha-like; GFRAL; GRAL; C6orf144

表达区间及表达系统（Source）

Biotinylated Human GFRAL/GFR alpha-like Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ser19-Glu351.[Accession | Q6UXV0]

分子量大小（Molecular Weight）

The protein has a predicted MW of 40.7 kDa. Due to glycosylation, the protein migrates to 48-62 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）

ELISA Data: Immobilized Human GDF15, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human GFRAL, His Tag with the EC50 of 89.1ng/ml determined by ELISA 

Blocking Data: Serial dilutions of Anti-GDF15 Antibody were added into Human GDF15, His Tag : Biotinylated Human GFRAL, His Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 40.8ng/ml.

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