表達區(qū)間及表達系統(tǒng)（Source） |
Recombinant Biotinylated Human DKK1 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Thr32-His266.[Accession | O94907] |
|
分子量大小（Molecular Weight） |
The protein has a predicted MW of 28.5 kDa. Due to glycosylation, the protein migrates to 40-50 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） |
ELISA Data: Immobilized Biotinylated Human DKK1, His Tag at 5μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human LRP-6, mFc Tag with the EC50 of 3.2ug/ml determined by ELISA. |
|
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. |
儲存條件
The product should be stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~8 °C under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
