• FluoroVue™ Nucleic Acid Gel Stain (10,000X)
• 500 µl / 500 µl x 5
  

Description 
The FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard for its user. It is a fluorescent stain which offers high sensitivity detection of double-stranded or single-stranded DNA and RNA in a convenient manner. The FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity (Table 1 and Fig. 2) that is several times greater than EtBr. 

Table 1. Different staining methods for using the FluoroVue™ Nucleic Acid Gel Stain

 For detailed protocols ofdifferent stainingmethods: please see pages 5~7. We recommend using an in-gel staining method for optimal effect. 1 With a mini horizontal gel electrophoresis system: Combine 40 ml of agarose gel with 300 ml running buffer. The regular post staining buffer volume is 100 ml. 2 Sensitivity is evaluated according to the 4 kb band of DM3100 

FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional ultra violet gel-illumination systems as well as the harmless long wave length blue light illumination systems, like B-BOX™. When bound to nucleic acids, the FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maxima of ~250 and ~482 nm, and an emission maximum of ~509 nm (Fig. 2). Therefore, it can replace EtBr without the need for changing existing lab imaging systems.

Fig. 2. The FluoroVue™ Nucleic Acid Gel Stain shows a green-yellow fluorescence under blue light excitation. The sensitivity of NS1000 is about 0.14 ng (arrow) for a 4 kb fragment. 

Caution 

Dispose of the stain in accordance to local rules and regulations. The fluorescent staining dye stock solution should be handled with particular caution because the solvent is known to facilitate the entry of organic molecules into tissues. There is no data that addresses the mutagenicity or toxicity of the fluorescent dye in humans. However, the fluorescent dye binds to nucleic acids, thus it should be recognized as a potential mutagen and used with appropriate care.
