miScript miRNA Inhibitors are chemically synthesized, single-stranded, modified RNAs which specifically inhibit endogenous miRNA function after transfection into cells. miScript miRNA Inhibitors are available at cell-culture grade (>90% purity) or animal grade (HPLC purified). miScript miRNA Inhibitors are also available phosphorothioate modified at the 20 nmol scale. For flexible screening, miScript miRNA Inhibitor Plates enable researchers to order any predesigned or custom-designed miScript miRNA Inhibitors in their choice of layout in 96-well or 384-well plates. miScript miRNA Mimics can be used for similar experiments.
