表達區間及表達系統（Source）

Human GPA Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Ser20-Glu91.[Accession | P02724-1]

分子量大?。?/font>Molecular Weight）

The protein has a predicted MW of 34.7 kDa. Due to glycosylation, the protein migrates to 45-70 kDa based on Tris-Bis PAGE result.

內毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

純度（Purity）

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

              活性（Activity）

SPR Data: Anti-GPA Antibody immobilized on CM5 Chip can bind Human GPA, hFc Tag with an affinity constant of 0.72 μM as determined in SPR assay

制劑（Formulation）

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.

重構方法（Reconstitution）

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