Administration Route
Output Type Fluorescence microscopy mRNA imaging (TO emission); compare +dox vs -dox
Output Value Higher fluorescence in +dox vs -dox by visual inspection, but spot-like fluorescence present in both conditions.
Output Units
Output Notes Compared to SAP(E)_FIT-DNA1, PNA conjugate appeared to give higher target-dependent signal but still with background spots.
