Recombinant Biotinylated Human Oncostatin M/OSM Protein,His-Avi Tag

Description :
Synonyms Oncostatin M;; MGC20461; Source Biotinylated Human Oncostatin M/OSM Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ala26-Arg221.[Accession | P13725] Molecular Weight The protein has a predicted MW of 25.1 kDa. Due to glycosylation, the protein migrates to 30-40 kDa based on Tris-Bis 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 LIF R, His Tag immobilized on CM5 Chip can bind Biotinylated Human Oncostatin M, His Tag with an affinity constant of 0.94 M as determined in SPR assay . Formulation Lyophilized from 0.22m 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.
