Administration Route
Output Type Fluorescence microscopy mRNA imaging (TO emission); compare +dox vs -dox
Output Value Spot-like fluorescence in +dox and -dox; smaller spots than penetratin; only modest/uncertain target-dependent increase.
Output Units
Output Notes Visual inspection suggested lower artefacts than penetratin but still substantial spots leading to background.
Toxicity Notes
Curation Notes
