CelGreen nucleic acid gel stain *10,000× concentrate in water* is a fluorescent dye with a unique involvement that binds to all dsDNA double helix sulcus regions.In the free state, the side strand and CelGreen emit weak fluorescence, but the fluorescence is greatly enhanced once they are combined with the double-stranded DNA. Therefore, the fluorescence signal strength of CelGreen is related to the amount of double-stranded DNA, and the amount of double-stranded DNA in the PCR system can be detected according to the fluorescence signal.

SYBR Green I is an asymmetrical cyanine dye, which is used to detect nucleic acids. It consists of a N-alkylated benzothiazolium or benzoxazolium ring system, that is joined by a monomethine bridge to a pyridinium or quinolinium ring system. SYBR Green I binds to the minor groove of dsDNA and is excited at a wavelength of 480 nm. It has a peak fluorescence emission of 520 nm.
