Product Propertie Alternative Names PDGF-D, SCDGF-B, IEGF, SCDGFB Species Human Expression Sequence Arg19-Arg370 Accession Q9GZP0-1 Tag N-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 41.82 kDa. Due to glycosylation, the protein migrates to 50-65 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 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder 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 ~ -15℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃, valid for 3 months.
