DMS therapy and SHAPE assays with various timescale reacting reagents have offered outstanding and reproducible information [179]. Experimental details on the dimethyl sulfate (DMS) and N-methyl isatoic anhydride (NMIA) probing assays are described beneath.Pharmaceuticals 2021, 14,Pharmaceuticals 2021, 14, x FOR PEER REVIEW8 of5 ofFigure two.
