Recombinant Cynomolgus IL-13Ra1 Protein,His Tag

Description :
Synonyms IL-13 R alpha 1; CT19; IL13RA; NR4 Source Cynomolgus IL-13Ra1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ala25-Thr341.[Accession | XP_005594500.1] Molecular Weight The protein has a predicted MW of 37.59 kDa. Due to glycosylation, the protein migrates to 55-70 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 SDS-PAGE and HPLC. Activity SPR Data: Cynomolgus IL-13Ra1,His Tag immobilized on CM5 Chip can bind Cynomolgus IL-13, His Tag with an affinity constant of 21.16 nM 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.
