Specification Source Biotinylated Human IFN gamma/IFNG Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Gln24-Gly161.[Accession | P01579] Molecular Weight The protein has a predicted MW of 19.1 kDa. Due to glycosylation, the protein migrates to 25-40 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by Tris-Bis PAGE Activity ELISA Data: Immobilized Human IFNGR1, hFc Tag at 1 μg/ml (100 μl/well) on the plate. Dose response curve for Biotinylated Human IFN gamma, His Tag with the EC50 of 39.1 g/ml determined by ELISA. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage 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. Caution 1.Please operate with lab coats and disposable gloves,for your safety. 2.This product is for research use only.
