分子別名（Synonyms）

GDNFR; GFRA1;GDNFRA; RET1L

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human GFR alpha 1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp25-Ser424.[Accession | NP_665736.1]

分子量大小（Molecular Weight）

The protein has a predicted MW of 45.8 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on SDS-PAGE result.

內(nèi)毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

純度（Purity）

> 95% as determined by SDS-PAGE and HPLC.

活性（Activity）

ELISA Data: Immobilized Human GDNF, No Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human GFR alpha 1, His Tag with the EC50 of 5.0ng/ml determined by ELISA.

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(gòu)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.
