Research Use Only

The Dicer Fluorogenic Assay Kit is a homogeneous 384-well assay designed to measure the double-stranded-RNA processing activity of Dicer for screening and profiling applications. The Dicer Fluorogenic Assay Kit contains enough purified Dicer, substrate, and assay buffer for 384 reactions. The assay relies on an RNA duplex imitating pre-miRNA, containing a conjugated fluorophore and quencher pair. Fluorescence of the dye is effectively quenched by the proximity of the quencher in the intact RNA duplex. The endoribonuclease Dicer processes the pre-miRNA into a mature 22 bp double-stranded miRNA by cleaving the 5 end which is conjugated to the dye, releasing it from the miRNA. Separated from the quencher, the dye emits fluorescence with excitation/emission maxima of lambda=647/ 665 nm. Dicer activity is proportional to the increase in fluorescence.
