DNA stains and ladders

Midori Green DNA stain is a safe alternative to Ethidium Bromide, with multiple safety tests conducted on it. Midori Green is flexible and affordable.

  • Replaces EtBr in all staining applications
  • No need to change protocols - add 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), Midori Green Xtra (optimized for Blue/GreenLED light), and Midori Green agarose tablets

Midori Green - safe DNA stain

The safe alternative to Ethidium Bromide

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 tests:

  • Ames test
  • Cytotoxicity
  • Cell membrane permeability
  • Hazardous waste screening
  • Latex glove penetration test

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 improves cloning efficiency.

Midori Green Agarose Tablets

Midori Green Agarose Tablets are a quick and easy solution for preparing agarose gels. The agarose tablet is dissolved in pure water, heated and poured into the gel tray. The popular Midori Green DNA Stain, TBE powder and agarose are all included and only the addition of water is necessary. Also, these tablets are very stable at room temperature.
