Recombinant Cynomolgus GFRAL/GFR alpha-like Protein,His-Avi Tag

Description :
Synonyms GRAL; GFRAL;GFR alpha-like; GFR alpha like Source Cynomolgus GFRAL/GFR alpha-like Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Gln20-Glu351.[Accession | XP_015304775.2] Molecular Weight The protein has a predicted MW of 40.7 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on 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 ELISA Data: Immobilized Cynomolgus GFRAL, His Tag at 1g/ml (100l/well) on the plate. Dose response curve for Cynomolgus GDF15, hFc Tag with the EC50 of 3.6ng/ml determined by ELISA. Formulation Lyophilized from 0.22m filtered solution in 20mM PB, 0.4M NaCl (pH 6.0). 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 20mM PB, 0.4M NaCl (pH 6.0).
