Specifications Synonyms VEGF; VEGFA; MVCD1; VAS; VEGFMGC70609; VPF; RP1-261G23.1; MGC70609;VEGF-165 Source FITC-Labeled Human VEGF165 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ala27-Arg191.[Accession | P15692-4] Source The protein has a predicted MW of 22.2 kDa. Due to glycosylation, the protein migrates to 28-33 kDa under reduced (R) condition, 45-55 kDa under Non reducing (N) condition based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: Immobilized FITC-Labeled Human VEGF165, His Tag at 0.2μg/ml (100μl/well) on the plate. Dose response curve for Anti-VEGF165 Antibody, hFc Tag with the EC50 of 22.3ng/ml determined by ELISA. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage 1.The product should be stored at -25~-15℃ for 1 year from date of receipt. 2.2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3.3 -6 months, -85~-65℃ under sterile conditions after reconstitution. 4.Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
