Recombinant Human IL-13Ra1 Protein,His Tag

Description :
Source Recombinant Human IL-13Ra1 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Ala27-Thr343.[Uniprot |P78552-1] Molecular Weight The protein has a predicted MW of 37.7 kDa. Due to glycosylation, the protein migrates to 50-70 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 Tris-Bis PAGEandHPLC Activity SPR Data: Human IL-13, His Tag immobilized on CM5 Chip can bind Human IL-13Ra1, His Tag with an affinity constant of 1M as determined in a 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 tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
