                            Description

                            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 to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr. 

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

                            Working Reagent Preparation

                            1:10,000 dilution in TAE or TBE buffered agarose 

                            Odoo - Sample 1 for three columns

                            In- gel staining

                            This protocol is highly recommended.

                            1. Prepare TAE or TBE buffered molten agarose solution.

                            40 ml molten agarose solution can cast two mini-gels (5.4 x 5.9 cm) or one landscape-gel (10.9 x 5.9 cm).

                            2. Dilute FluoroVue™ Nucleic Acid Gel Stain 10,000X with the molten gel solution and mix well prior to being poured into the gel. 

                            For example: 4 μl in 40 ml molten agarose solution

                            3. Cool the molten agarose solution until it can be handled by hand and then pour it into gel tray.

                            Casted gels are stable at 4°C for 3 days in dark. After three days the sensitivity will decrease daily. 

                            4. Perform agarose gel electrophoresis (avoid light).

                            The recommended voltage is 4–10 V/cm (distance between anode and cathode). Avoid using high voltage during electrophoresis. High voltage causes excess heat and affects the dye adversely. 

                            During electrophoresis, the staining dye runs toward the anode, therefore DNA bands with smaller molecular weights may be weaker in intensity due to less staining dye. 

                            5. Visualize or photograph the gel with UV or blue-light illumination (blue-light is recommended).

                            Clean the surface of the illuminator before and after each use with deionized water. Accumulation of fluorescent dyes on the surface will create a high fluorescent background.

                            Video cameras and CCD cameras have a different spectral response compared to the black-and-white print film and therefore may not exhibit the same sensitivity.

                            Staining during electrophoresis

                            The sensitivity of this method is slightly lower than the in-gel staining.

                            1. Prepare agarose gel following your standard protocol.

                            2. Dilute FluoroVue™ Nucleic Acid Gel Stain 10,000 folds into the running buffer and mix well.

                            For example: 30 μl in 300 ml running buffer 

                            3. Perform agarose gel electrophoresis (avoid light).

                            During electrophoresis, the staining dye runs toward the anode.

                            4. Visualize or photograph the gel with UV or blue-light illumination (blue-light is recommended).

                            Clean the surface of the illuminator before and after each use with deionized water. Accumulation of fluorescent dyes on the surface will create a high fluorescent background.

                            Video cameras and CCD cameras have a different spectral response compared to the black-and-white print film and therefore may not exhibit the same sensitivity.

                            Staining after electrophoresis (post-staining)

                            Post-staining method is recommended for polyacrylamide electrophoresis, due to the longer time required for running PAGE. The sensitivity of this method is lower than the in-gel staining method.

                            1. Performing agarose gel electrophoresis following your standard protocol.

                             2. Dilute FluoroVue™ Nucleic Acid Gel Stain 10,000 folds into the TE, TAE, or TBE buffer and mix well.

                            For example: 10 μl in 100 ml TAE buffer 

                            Use a plastic container. Glass containers are not recommended, as they absorb fluorescent dye in staining solution. 

                            Protect the staining container from light by covering it with aluminium foil, or place it in the dark.

                            The staining solution can be stored for up to one week or more.

                            3. Immerse the gel in a staining solution (1X) and incubate at room temperature for 10 - 30 minutes. (avoid light).

                            Staining time varies with the thickness of the gel and percentage of agarose. If needed, agitate the gel gently at room temperature to shorten staining time. 

                            4. Visualize or photograph the gel with UV or blue-light illumination (blue-light is recommended).

                            Clean the surface of the illuminator before and after each use with deionized water. Accumulation of fluorescent dyes on the surface will create a high fluorescent background.

                            Video cameras and CCD cameras have a different spectral response compared to the black-and-white print film and therefore may not exhibit the same sensitivity.
