The main difference between GelRed™ and GelGreen™ is their fluorescence excitation and emission wavelengths. GelRed™ has red fluorescence, similar to ethidium bromide. GelGreen™ has green fluorescence, similar to SYBR® Green or SYBR® Safe. Both dyes are compatible with standard UV transilluminators. GelGreen™ is also compatible with blue light transilluminators, which allow users to avoid exposing themselves and their DNA samples to ultraviolet radiation.
GelRed™ and GelGreen™ have higher sensitivity for double stranded nucleic acids compared to single stranded nucleic acids, but GelRed™ is more sensitive for staining single stranded nucleic acids than GelGreen™. GelRed™ is about twice as sensitive for double stranded nucleic acids compared to single-stranded nucleic acids, and about five times more sensitive than GelGreen™ for staining single stranded nucleic acids.
