Cynomolgus GDF15 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus GDF15 Protein is expressed from HEK293 with hFc tag at the N-Terminus.
It contains Ala197-Val308 [Accession | G7PWZ3].

分子量大小(Molecular Weight)

The protein has a predicted MW of 37.9 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.

纯度(Purity)

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

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

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.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

ELISA Data

Immobilized Cynomolgus GFRAL, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Cynomolgus GDF15, hFc Tag with the EC50 of 3.5ng/ml determined by ELISA.

背景(Background)

Growth and differentiation factor 15 (GDF15) is an inflammation-associated hormone with poorly defined biology. Here, we investigated the role of GDF15 in bacterial and viral infections. Inflammation induced GDF15, and that GDF15 was necessary for surviving both bacterial and viral infections, as well as sepsis. The protective effects of GDF15 were largely independent of pathogen control or the magnitude of inflammatory response, suggesting a role in disease tolerance.
