Fluorescent Red Mega 500

Mega dyes are specifically designed for multicolor techniques. Fluorescent red Mega 500 is characterized by an extremely large stoke′s shift between excitation and emission maxima. This dye is especially well suited for excitation by argon lasers or other short wavelength light sources and can be excited using the same light source or filter settings as for fluorescein and other widely used dyes.

Fluorescent red Mega 500 and other Mega dyes are specifically designed for multicolor techniques. It is characterized by an extremely large stoke′s shift between excitation and emission maxima. This dye is especially well suited for excitation by argon lasers or other short wavelength excitation light. This means that it can be excited with the same light source or filter arrangement than fluorescein and other widely used dyes as well as other Mega dye. Due to the different emission wavelength several different labels can be detected independently in the same experiment. Due to the small size of the Mega-labels and the direct conversion of excitation light into emission without using a FRET mechanism we foresee a variety of possible applications including DNA sequencing and FISH microscopy.
