Recombinant Human IL-1RL1/ST2 Protein,hFc Tag

Description :
Synonyms ST2;FIT-1;DER4;IL1RL1 Source Human IL-1RL1/ST2 Protein is expressed from HEK293 with hFc tag at the C-terminus. It contains Lys19-Phe328.[Accession | Q01638-2] Molecular Weight The protein has a predicted MW of 61.75 kDa. Due to glycosylation, the protein migrates to 75-100 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 Human IL-33, No Tag at 2g/ml (100l/well) on the plate. Dose response curve for Human IL-1RL1, hFc Tag with the EC50 of 9.9ng/ml determined by ELISA. Formulation Lyophilized from 0.22 m 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.
