References

dsGreen, an equivalent of SYBR® Green I is a sensitive dsDNA binding dye, which can be used for routine DNA detection in agarose and polyacrylamide gels. A qPCR grade reagent is also available.

Unlike ethidium bromide, dsGreen is highly selective towards double stranded DNA, much less harmful, and offers better sensitivity.

Comparison between ethidium bromide and dsGreen

Feature	Ethidium Bromide	dsGreen
Fluorescence	Red (615 nm)	Green (524 nm)
Excitation maximum	302 nm	454 nm
Excitation light source	UV only	Blue light or UV
Sensitivity	2 ng / band (dsDNA) 100 ng / band (RNA)	0.08 ng / band (dsDNA) 1–2 ng / band (oligonucleotides)
Health hazard	High	Low

Recommended protocol

DNA Staining in Gels with dsGreen or SYBR Green I
