Data Sheet
Description SafeView™ products represent a new and safe class of nucleic acid stains for the visualization of double-stranded DNA, single-stranded DNA, and RNA in agarose and polyacrylamide gels. The dyes are developed to replace toxic Ethidium Bromide (EB, a potent mutagen), commonly used in gel electrophoresis for visualization of nucleic acids in agarose and polyacrylamide gels. SafeView™ products are non-carcinogenic by the Ames-test. The results are negative in both the mouse marrow chromophilous erythrocyte micronucleus and mouse spermary spermatocyte chromosomal aberration tests.
Application Safe Detection of dsDNA, ssDNA and RNA in agarose and polyacrylamide gels. Both Safeview Classic and Safeview Plus will work with blue light.

Storage 4°C
Notes Dispose SafeView™ Classic as you would any other non-carcinogenic fluorescent dye (eg. Acridine orange; Propidium iodide). This product is distributed for laboratory research only. Caution: Not for diagnostic use .

  Question:
  Email:        
Can SafeView be a replacement for ethidium bromide? Can I do gel extraction with it?
SafeView can be used as a replacement for ethidium bromide as they both work on general agarose. We recommend using SafeGreen for downstream cloning applications as SafeView can interfere with the ligation reaction, yielding fewer colonies.
How does SafeView work and how come it is not carcinogenic?
There are fluorescent compounds in SafeView and these fluorescent compounds have the capability to bind to DNA. There may be some unknown effects of SafeView that have not been documented but that applies to the SYBR set as well; however, SafeView products are definitely not as carcinogenic as ethidium bromide.
How do I use SafeView products?
The Safe-(Red, Green and White) loading dyes work the same as 6x loading dye, loaded with the sample. SafeView Classic is used directly in the gel and the running buffer.
Does the SafeView differentiate double stranded nucleic acid and single stranded nucleic acid? Does the Safe-(Red, Green and White) work the same way?
Under UV, SafeView Classic emits a green fluorescence when bound to both single and double stranded DNA templates, therefore they cannot be differentiated by this method. It will emit a red fluorescence when bound to RNA templates.
The SafeView Stains (Red, Green and White) do not perform in this way and will stain all nucleic acid templates one color.
At what temperature do I store the SafeView products?
All the SafeView products should be stored at four degrees Celsius.
Do I need a special filter for photography of DNA gels stained with SafeView?
Under UV light, SafeView Classic emits a green fluroescence when bound to both single and double stranded DNA templates. It will emit a red fluorescence when bound to RNA templates. No filter is necessary for viewing these colours, however a filter may be needed for photographing the gel.
How long does the SafeView Classic stain last in a gel?
Our in-house testing has shown that SafeView stained gels (>10ng DNA loaded per lane) can still be effectively visualized up to 1 week later with only a slight decrease in brightness. Gels should be stored properly to maintain a good signal, at 4C in the dark, sealed in a plastic bag or pouch with wet paper towel loosely wrapped around the gel.
Why is SafeView (G-108) stain not working on my samples?
Make sure you are following the protocol carefully. It is critical that both buffer and gel have SafeView dye in them otherwise it will not work. This is different from ethidium bromide. You can consider to add 2.5ul of SafeView (instead of 5ul) for every 100ml of running buffer, which will reduce background fluorescence and allow the bands to show with more contrast.
How long does it take to the stain to dissociate from Nucleic Acids?
It will take one hour of washing with water.
Is it degradable, if so how fast and under what circumstances?
2 hours over 100C
What is the sensitivity of the dyes?
Safe-Green has Excitation Wavelength of 290nm and Emission Wavelength of 490nm, and its sensitivity is range between 0.2-0.6ng
Safe-Red has Excitation Wavelength of 490nm and Emission Wavelength of 630nm, and its sensitivity is range between 0.3-0.8ng
Safe-White has Excitation Wavelength of 320nm and Emission Wavelength of 480nm, and its sensitivity is range between 0.2-0.5ng
SafeView Classic emits green fluorescence when bound to dsDNA and ssDNA and red fluorescence when bound to RNA. This stain has one excitation (290 nm) and two emission spectra (490 nm and 605 nm) and the sensitivity range is between 0.1-0.3ng.
SafeView Plus has Excitation Wavelength of 490nm and Emission Wavelength of 520nm and the its sensitivity is range between 0.05-0.1ng
Can SafeView products be used post-stain?
Only SafeView Plus (G468) should be used in a post stain. SafeView classic and Safe Stains are not designed for post-staining. SafeView Classic must be added to the gel and the running buffer prior to the loading of the samples. Safe-(Red, Green and White) stains must be added to the sample before loading it to the gel.
Why is the EtBr signal stronger in the pictures when I compare SafeView with EtBr?
A reason for this is that most gel doc systems have been optimized for EtBr so that is why the EtBr signal is so strong in the pictures.
We see shifting and migration of the DNA fragments. What are the recommendations to minimize this?
Shifting is unavoidable and quite natural for such fragments, regardless of the staining any . We suggest to use SafeGreen ladders, which will give accurate molecular weight with no additional staining agents needed.

I cannot see 100bp and 200bp bands on a 1% gel. What should I do?
It is very difficult to detect 100bp and 200bp bands in 1% gel with any stains. Higher gel concentrations should be used, such as 2% agarose.
Can I use SafeView products in Polyacrylamide gels?
Yes, we have tested our SafeView products for this application.
How do I dispose Agarose Gels stained with Safeview and how do I dispose buffers and gloves?
Dispose SafeView™ Classic as you would any other non-carcinogenic fluorescent dye (eg. Acridine orange; Propidium iodide).

All gels and contaminated “non-sharp” lab debris (e.g., gloves, pads, towels, tubes, etc.) that are processed using this dye can be discarded in the trash.

Spent running buffer solutions and destaining solutions that contain the dyes can either be collected and disposed of through the HWMU or collected and run through an approved filter device.

The buffer solutions that have been run through the approved filter should be checked under the appropriate light source for complete removal of the dyes, and if it passes (does not fluoresce), the liquid can be disposed of down the drain with a copious amount of water as long as no other materials are present that would cause the material to be a Hazardous Waste.

The filters that have been used up and are no longer effective must be disposed of through the HWMU.
Do SafeView products give problems in the process of cloning?
We recommend using Safe-Green (G108-G) for downstream cloning applications, as testing has shown it yields more colonies following the ligation reaction than SafeView (G108).
What device do you use to see the electrophoresis bands?
We use both UV and LED transilluminators, our gel QC pictures in PCR department are taken with UV.
Will staining appear the same when using UV light and LED (same colors)?
UV and LED will give the same colors.
