Recombinant Rat IL-22R alpha 1 Protein,His Tag

Description :
Synonyms IL-22R-alpha-1; IL-22RA1; CRF2-9; IL22R; IL22R1; IL-TIF-R1; zcytoR11 Source Rat IL-22R alpha 1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains His16-Ala228.[Accession | NP_001178798.1] Molecular Weight The protein has a predicted MW of 25.42 kDa. Due to glycosylation, the protein migrates to 37-45 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 SPR Data:Rat IL-22R alpha 1, His Tag immobilized on CM5 Chip can bind Biotinylated Mouse IL-22, His Tag with an affinity constant of 0.145 M as determined in SPR assay . 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.
