Product and properties Synonyms CD257; BLyS;BAFF; TNFSF20 Source Biotinylated Cynomolgus BAFF/TNFSF13B/CD257 Trimer Protein is expressed from HEK293 with His tag and Flag tag and A vi tag at the N-Terminus. It contains Thr141-Leu285.[Accession | A0A2K5V2X4] Molecular Weight The protein has a predicted MW of 54.2 kDa. Due to glycosylation, the protein migrates to 55-60 kDa based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE Activity ELISA Data: Immobilized Biotinylated Cynomolgus BAFF (Trimer) , His Tag at 5μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human BAFFR, hFc Tag with the EC50 of 17.4ng/ml determined by ELISA. Formulation Lyophilized from 0.22μm 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
