The structure and activity of the purified Dicer were assessed by size-exclusion chromatography coupled to multi-angle light-scattering and refractive index (SEC-MALS/RI), negative stain transmission electron microscopy (TEM), binding assay and steady-state kinetics. Our kinetic analysis for Dicer cleavage of the pre-let-7a-1 substrate were performed under strict steady state conditions and reveals k cat and K M values that are much higher than previously reported. Moreover, SEC -MALS/RI analysis of a purified Dicer sample stored for 6 months at − 80°C in sucrose/DDM-containing buffer shows that the purified protein remains almost exclusively monomeric ( ≥ 94%), indicating that the protein is intact after long-term storage (Additional file 1: Figure S1 ). ./cache/cord-288093-012ipcdr.txt ./txt/cord-288093-012ipcdr.txt
