Recombinant Human FGFR2 beta (IIIb) Domain Protein,hFc Tag

表达区间及表达系统（Source）

Human FGFR2 beta (IIIb) Domain Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Pro253-Glu378.[Accession | P21802-3]

分子量大小（Molecular Weight）

The protein has a predicted MW of 40.5 kDa. Due to glycosylation, the protein migrates to 60-68 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 FGFR2 beta (IIIb) Domain, hFc Tag at 0.5μg/ml (100μl/Well)

on the plate. Dose response curve for Biotinylated Anti-FGFR2 (IIIb) Antibody,hFc Tag with the EC50 14.3ng/ml determined by ELISA.

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.
