Recombinant Human IL-18BP Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Thr31-Gly194.[uniprot | O95998-2] |
|
分子量大?。?/font>Molecular Weight） |
The protein has a predicted MW of 44.4 kDa. Due to glycosylation, the protein migrates to 60-80 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） |
ELISA Data: Immobilized Human IL-18 at 5μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-18BP, hFc Tag with the EC50 of 36.5ng/ml determined by ELISA SPR Data: Human IL-18BP, hFc Tag captured on Protein A chip, can bind Human IL-18 with an affinity constant of 0.04nM as determined in a 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. |
