Recombinant Cynomolgus IL-31 Protein,His Tag

Description :
Synonyms Interleukin-31;;IL31; Source Cynomolgus IL-31 Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Leu27-Thr163.[Accession | G7PJ78-1] Molecular Weight The protein has a predicted MW of 16.5 kDa. Due to glycosylation, the protein migrates to 23-30 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 IL-31 RA, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-31, His Tag with an affinity constant of 0.715 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.
