表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source） |
Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Ala27-Thr343.[Uniprot | P78552-1] |
|
分子量大小 （Molecular Weight） |
The protein has a predicted MW of 37.7 kDa. Due to glycosylation, the protein migrates to 50-70 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: Human IL-13, His Tag immobilized on CM5 Chip can bind Human IL-13Ra1, His Tag with an affinity constant of 1μM as determined in a 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. |
