Product Description
Product Properties Property Name Property Details Alternative Names notch ligand DLL4, Delta-like 4, MGC126344, DLL4 Species Human Expression Region Ser27–Pro524 Accession Q9NR61 Tag No Tag Expression System HEK293 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
