Biotinylated Human IL-18BP Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Thr31-Gly194.[Accession | O95998-1] |
|
分子量大?。?/font>Molecular Weight） |
The protein has a predicted MW of 20.5 kDa. Due to glycosylation, the protein migrates to 52-65 kDa based on Tris-Bis PAGE result. |
|
內(nèi)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: Biotinylated Human IL-18BP, His Tag captured on CM5 Chip via anti-his antibody can bind Human IL-18, No Tag with an affinity constant of 0.90 nM as determined in SPR assay |
|
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 tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
