Molecular Weight |
The protein has a predicted MW of 54.28 kDa. Due to glycosylation, the protein migrates to 55–70 kDa based on SDS-PAGE result. |
|
Purity |
> 95% as determined by SDS-PAGE and HPLC. |
|
Endotoxin |
< 1.0 EU per μg by the LAL method. |
|
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS, 200 mM Arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
|
Appearance |
Lyophilized Powder |
|
Bioactivity |
【ELISA Data】 Immobilized Human DLL4, No Tag at 0.5 μg/mL (100 μL/well) on the plate. Dose response curve for Anti-DLL4 Antibody, hFc Tag with the EC50 of 8.7 ng/mL determined by ELISA. |
|
Reconstitution |
Centrifuge the vial before opening. Reconstitute lyophilized protein using distilled water at a concentration above 100 μg/mL. It is recommended to aliquot the reconstituted protein for single-use to avoid repeated freeze-thaw cycles. |
Features
High purity, high bioactivity, low endotoxin, excellent lot-to-lot consistency
