Eleven DNA dyes were compared for real-time loop-mediated isothermal amplification.
SYTO-81 and SYTO-82 had the highest fluorescence enhancement.
SYTO-81 had the widest range of working concentrations.
These dyes were better suited for detection with simple optical setup (Gene-Z).
Gene-Z was used to detect 10 copies of M. tuberculosis DNA in less than 10 min.
