MidoriGreen DNA stain - the safe alternative to Ethidium Bromide

Midori Green is safe

Midori Green was developed to offer a non-carcinogenic and less mutagenic dye for DNA electrophoresis. In addition, Midori Green displays a high sensitivity for small fragments as well as a superior signal to noise ratio. Midori Green Advance can be used just like EtBr by adding it directly to agarose and is compatible with regular UV tables as well as with new Blue LED or Blue/Green LED tables and instruments.

Midori Green is the only safe DNA stain on the market with a complete safety profile. Ask your supplier if your current "safe" DNA stain has passed these test:

  • Ames test
  • Acute oral toxicity test
  • Mouse bone marrow micronucleus test
  • Chromosome aberration test
  • Latex and nitrile glove penetration test

Midori Green is flexible and affordable

  • Midori Green replaces EtBr in all staining applications
  • No need to change protocols - add Midori Green to gels or use as loading buffer
  • Compatible with UV boxes and Blue/Green LED technology
  • Available as Midori Green Advance (mix-in with agarose gel), Midori Green Direct (mix-in with sample) and Midori Green agarose tablets

Midori Green helps you clone your DNA

When used in combination with Blue/Green LED transilluminators, Midori Green results in significantly less damage when cutting DNA from agarose gels and hence dramatically improved cloning efficiency.
