#### There is no need to choose between safety and excellent results.

[MIDORI Green Xtra](https://www.nippongenetics.eu/en/produkte/electrophoresis-dna-rna/nucleic-acid-stains/midori-green-xtra/) is the safe alternative to the traditional nucleic acid stain **ethidium bromide**.

 

## 1) No toxicity and non-carcinogenic − for your personal health

The innovative nucleic acid stain is non-carcinogenic, non-mutagenic and non-toxic and therefore not harmful for your health. Independent laboratories confirmed its safety: Both, the mutagenicity test (Ames-Test) and the cytotoxicity test were negative.

 

## 2) Very high sensitivity − for excellent signals, better than ethidium bromide

MIDORI Green Xtra leads to unbeatable fluorescence signals of nucleic acids. The direct comparison with the popular DNA dyes GelRed® and SYBR® Safe shows, that MIDORIGreen Xtra reaches new levels of sensitivity: Even the detection of the smallest quantities of DNA or RNA is possible.

 

## 3) Reduced background fluorescence − for highest efficiency and reliability

Agarose gels stained with MIDORIGreen Xtra have a very low background fluorescence which makes the identification of low amounts of DNA very easy.

 

## 4) High flexibility − for in-gel & post staining

MIDORI Green Xtra is suitable for in-gel and post-staining. There is no need to change the prefered procedure.

 

## 5) Optimal for Blue/Green LED technology − for secure illumination without UV light

MIDORI Green Xtra is optimized for Blue/Green and Blue LED light, leading to unbeatable fluorescence signals of DNA and RNA in agarose gels. In addition, UV-light is also suitable for the detection of nucleic acid, but less efficient than non-damaging visible light.
