Product Properties Alternative Names Interleukin-11,IL11,Adipogenesis inhibitory factor,AGIF,INN, Oprelvekin,Oprelvekin,IL-11Oprelvekin,interleukin 11,interleukin-11 Species Cynomolgus Expression Sequence Pro22-Leu199 Accession P20808 Tag N-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 20.48 kDa. Due to glycosylation, the protein migrates to 21-25 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity SPR Data:Human IL-11 R alpha, hFc Tag captured on CM5 Chip via Protein A can bind Cynomolgus IL-11, His Tag with an affinity constant of 0.25 nM as determined in SPR assay . Reconstitution Method Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 to -15°C. Once received, the product is valid for one year. After resuspension, store at -85 to -65°C. The product is valid for three months.
