Recombinant Human Interferon omega-1 Protein,His Tag

Description :
Synonyms IFN-1;IFNW1;Interferon alpha-II-1 Source Human Interferon omega-1 Protein is expressed from HEK293 with His tag at the C-terminus. It contains Leu22-Ser195.[Accession | P05000] Molecular Weight The protein has a predicted MW of 21.25 kDa. Due to glycosylation, the protein migrates to 25-30 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity SPR Data:Human IFNAR1, His Tag immobilized on CM5 Chip can bind Human Interferon omega-1, His Tag with an affinity constant of 20.96 M as determined in SPR assay . Formulation Lyophilized from 0.22 m 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 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
