表達區(qū)間及表達系統(tǒng)（Source） |
Cynomolgus IL-4 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains His25-Ser153.[Accession | P79339-1] |
|
分子量大?。∕olecular Weight） |
The protein has a predicted MW of 16.03 kDa. Due to glycosylation, the protein migrates to 23-28 kDa based on SDS-PAGE result. |
|
內(nèi)毒素（Endotoxin） |
Less than 1EU per μg by the LAL method. |
|
純度（Purity） |
> 95% as determined by SDS-PAGE and HPLC. |
|
活性（Activity） |
SPR Data:Cynomolgus IL-4, His Tag immobilized on CM5 Chip can bind Cynomolgus IL-4 R alpha, His Tag with an affinity constant of 13.48 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. |
|
