Recombinant Biotinylated Human GDF15 Protein,His-Avi Tag

Description :
Source Biotinylated Human GDF15 Protein is expressed from E.coli with His tag and Avi tag at the N-terminal. It contains Ala197-Ile308.[Accession |Q99988-1] Molecular Weight The protein has a predicted MW of 15.19 kDa same as Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGE Activity ELISA Data: Immobilized Human GFRAL, hFc Tag at 1g/ml (100l/Well) on the plate. Dose response curve for Biotinylated Human GDF15, His Tag with the EC50 of 17.5ng/ml determined by ELISA. Formulation Lyophilized from 0.22m filtered solution in 50mM HAc (pH 2.9). 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 50mM HAc (pH 2.9).
