Recombinant Human IL-37 Protein

Description :
Synonyms IL-1F7;IL-1H4;IL-1X;FIL1 zeta Source Human IL-37 Protein is expressed from E.coli without tag. It contains Lys27-Asp192.[Accession | Q9NZH6-2] Molecular Weight The protein has a predicted MW of 18.55 kDa same as 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 IL-18BP, hFc Tag captured on CM5 Chip via Protein A can bind Human IL-37, No Tag with an affinity constant of 0.12 M as determined in SPR assay . Formulation Lyophilized from 0.22m filtered solution in 20mM PBS, 2mM DTT (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.
