Recombinant Biotinylated Human BAFF/TNFSF13B/CD257 Trimer Protein,His-Avi Tag

Description :
Source Biotinylated Human BAFF/TNFSF13B/CD257 Trimer Protein is expressed from HEK293 with His tag and Avi tag at the N-terminal. It contains Thr141-Leu285.[Accession |Q9Y275-1] Molecular Weight The protein has a predicted MW of 54.2 kDa. Due to glycosylation, the protein migrates to 55-68 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 Tris-Bis PAGE Activity ELISA Data: Immobilized Human BAFFR, hFc Tag at 5g/ml (100l/Well) on the plate. Dose response curve for Biotinylated Human BAFF (Trimer) , His Tag with the EC50 of 6.9ng/ml determined by ELISA. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% 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 distilled water.
