FAQs
| 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 why is it 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. | |
| 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 490nm and Emission Wavelength of 525nm, and its sensitivity range is between 0.2-0.6ng.Safe-Red has Excitation Wavelength of 540nm and Emission Wavelength of 630nm, and its sensitivity range is between 0.3-0.8ng.Safe-White has Excitation Wavelength of 370nm and Emission Wavelength of 470nm, and its sensitivity range is 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 (490 nm) and two emission spectra (520 nm and 635 nm) and the sensitivity range is between 0.1-0.3ng.SafeView Plus has Excitation Wavelength of 490nm and Emission Wavelength of 525nm and its sensitivity range is 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 may be stronger in the pictures. | |
| will I need an additional loading buffer for my samples? | |
The loading dye is included in the products. No additional loading buffer needed. | |
| We see migrations and band shifting of our fragments. Are there any recommendations that you can give us to minimize this band shifting? | |
Shifting is unavoidable and quite natural for any fragments, regardless of the staining agent. We suggest to use SafeGreen ladders, which will give accurate molecular weight with no additional staining agents needed.http://www.abmgood.com/DNA-Ladder-Safe-Green™-100bp-Opti-DNA-Marker-Invitroge-G473.htmlhttp://www.abmgood.com/DNA-Ladder-Safe-Green™-1kb-Opti-DNA-Marker-Invitroge-G474.html | |
| 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. We suggest using SafeGreen ladders, which will give accurate molecular weight with no additional staining agents needed.http://www.abmgood.com/DNA-Ladder-Safe-Green™-100bp-Opti-DNA-Marker-Invitroge-G473.htmlhttp://www.abmgood.com/DNA-Ladder-Safe-Green™-1kb-Opti-DNA-Marker-Invitroge-G474.html | |
| 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. | |
| Which of the Safe stains will work with blue light / LED? | |
All of our SafeView stains have been tested in-house to be compatible with UV light. SafeView Classic, SafeView Plus, and SafeGreen will also work under blue light/LED. SafeRed and SafeWhite will only work under UV light.Safe View Plus should only appear green. SafeView Classic will be red for RNA and green for DNA. | |
| What is the approved filter for eliminating the spent running buffer solutions? | |
Most facilities have approved the disposal of SafeView chemicals directly down the drain, with adequate water flushing or dilution, since SafeView™ products are non-carcinogenic. However, regulations vary between different regions, so please contact your local safety office for disposal guidelines specific to your area. You may review the MSDS of this product for more detailed information. | |

PCR(聚合酶链式反应）是利用DNA在体外摄氏95°高温时变性会变成单链，低温（经常是60°C左右）时引物与单链按碱基互补配对的原则结合，再调温度至DNA聚合酶最适反应温度（72°C左右），DNA聚合酶沿着磷酸到五碳糖(5'-3')的方向合成互补链。基于聚合酶制造的PCR仪实际就是一个温控设备，能在变性温度，复性温度，延伸温度之间很好地进行控制。

迷迭逆夏000692017-10-25
定量PCR仪主要由两部分组成，一个是PCR系统，一个是荧光检测系统。选择定量PCR仪的关键——由于定量PCR必需借助样本和标准品之间的对比来实现定量的，对于定量PCR系统来说，重要的参数除了传统PCR的温控精确性、升降温速度等等，更重要的还在于样品孔之间的均一性，以避免微小的差别被指数级放大。至于荧光检测系统，多色多通道检测是当今的主流趋势——仪器的激发通道越多，仪器适用的荧光素种类越多，仪器适用范围就越宽；多通道指可同时检测一个样品中的多种荧光，仪器就可以同时检测单管内多模版或者内标 样品，通道越多，仪器适用范围越宽、性能就更强大。
