Recombinant Human IL-1R2/IL-1 RII/CD121b Protein,hFc Tag

Description :
Synonyms IL-1RT2; IL-1RT-2;IL-1R-2; IL-1R-beta Source Human IL-1R2/IL-1 RII/CD121b Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Phe14-Glu343.[Accession | NP_004624.1] Molecular Weight The protein has a predicted MW of 64.4 kDa. Due to glycosylation, the protein migrates to 70-80 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 Activity ELISA Data: Immobilized Human IL-1 Beta, His Tag at 5g/ml (100l/Well) on the plate. Dose response curve for Human IL-1R2, hFc Tag with the EC50 of 0.44g/ml determined by ELISA . Formulation Lyophilized from 0.22m 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.
