51 个常见问题解答

使用SYBR Safe DNA凝胶染料染色，为什么我有时候会在凝胶内看到斑点？

很多衣服上的增白剂，以及某些真菌和细菌，和SYBR Safe DNA凝胶染料会发出同样波长的荧光。这些位于凝胶表面或凝胶内的污染物可能会产生斑点。

电泳时，SYBR Safe染料朝哪个方向迁移？

与溴化乙锭相似，SYBR Safe DNA凝胶染料与DNA的迁移方向相反。由于只有凝胶的最底部染料浓度会在电泳过程中降低，所以使用SYBR Safe DNA凝胶染料制备的凝胶没有实际影响。在电泳结束后用SYBR Safe DNA凝胶染料染胶，可部分抵消这种作用。染料溶液不应该加入到电泳缓冲液中，因为这可能会导致染料在电极上分解，并将有毒的挥发性化合物释放到空气中。

乙醇沉淀法能否去除SYBR Safe染料？

使用乙醇沉淀法可轻松去除核酸上的SYBR Safe DNA凝胶染料。

能否将SYBR Safe DNA凝胶染料重复用于第二块凝胶？

我们强烈不建议重复使用SYBR Safe DNA凝胶染料，因为这会大大降低灵敏度。

SYBR Safe DNA凝胶染料的实验兼容性和EB的相同吗？

SYBR Safe DNA凝胶染料与目前我们已经检测的所有下游应用兼容，包括从凝胶上切割PCR产物、凝胶纯化、Gateway克隆、TOPO克隆和限制性内切酶克隆。如果您想将SYBR Safe DNA凝胶染料用于特殊应用，请将详细信息发送到我们的邮箱techsupport@lifetech.com.

用SYBR Safe DNA凝胶染料进行的染色，还可使用哪些其他激发波长进行观察？

SYBR Safe DNA凝胶染料有两个主要的激发峰：紫外区的280nm和可见光区的502nm。因此，254 nm或300 nm紫外激发光以及488 nm激光、470 nm LED和广泛的蓝色光源（如Safe Imager蓝光透射仪（货号S37102））都能够有效激发。最大激发波长为502nm；因此，Safe Imager蓝光透射仪是激发SYBR Safe DNA凝胶染料的最佳选择。您可通过在线方式或在染料附带的实验方案中查看SYBR Safe DNA凝胶染料的全部激发和发射光谱。

使用溴化乙锭滤光片及其相机设置能否看到SYBR Safe DNA凝胶染料？

SYBR Safe DNA凝胶染料的最大发射波长为530 nm。因此一些溴化乙锭滤光片可以透过所有500 nm以上的光。这些滤光片（通常为黄色）及其相关相机设置适用于SYBR Safe DNA凝胶染料，通常只需对曝光或补光稍作调整。其他溴化乙锭滤光片（通常为红色）只能透过600 nm或以上的光；这些滤光片及其相关相机设置不适用于SYBR Safe DNA凝胶染料。

在无发射滤光片的紫外透射仪上能否看到条带？

使用SYBR Safe DNA凝胶染料染色的条带在300nm透射仪上是肉眼可见的。如果相机没有配备滤镜，激发光将被捕捉到图像上，以呈现“被冲洗”的外观。在您的CCD或相机上安装紫外兼容的发射滤光片，可得到最佳的凝胶成像结果。紫外灯也会发射一些红外（IR）光；如果您的相机镜头没有可阻断IR的特殊涂层，则需要安装红外滤镜，防止凝胶后面的紫外灯形成模糊图像。为了达到最佳检测和完全安全的目的，应使用Safe Imager蓝光透射仪。

对使用SYBR Safe DNA凝胶染料染色的DNA采用蓝光观察有什么优势？

与紫外光不同，蓝光可将DNA损害降至最低。相较于使用溴化乙锭染色并暴露于紫外光的DNA，使用SYBR Safe DNA凝胶染料和Safe Imager蓝光透射仪可提高克隆效率。

使用SYBR Safe DNA凝胶染料染色的DNA如何观察？

使用SYBR Safe DNA凝胶染料染色的DNA可使用蓝光透射仪观察，如我们的Safe Imager 2.0蓝光透射仪或标准紫外透射仪。如果您想要使用DNA进行克隆，应避免使用SYBR Safe DNA凝胶染料染色的DNA暴露于紫外光照射下。

1X染料溶液中，含多少SYBR Safe DNA凝胶染料（ppm）？

1X染料溶液中的SYBR Safe DNA凝胶染料含量低于1ppm。

可否在琼脂糖凝胶制胶时直接加入SYBR Safe DNA凝胶染料？

可以。只需在制备融化的琼脂糖时，用SYBR Safe DNA凝胶染料溶液替代缓冲液。如果您使用了10,000X SYBR Safe DNA凝胶染料浓缩液，则使用琼脂糖凝胶缓冲液（如1X TBE或1X TAE）以1:10,000稀释浓缩染料，并将缓冲液/染料溶液加入到琼脂糖粉末中。您可使用微波炉对琼脂糖/SYBR Safe DNA凝胶染料混合物进行短暂加热。

SYBR Safe染料与溴化乙锭有何区别？

SYBR Safe染料无致突变性、无毒性。SYBR Safe染料与溴化乙锭在紫外范围内具有相似的敏感度（约500 pg/条带）和同等的分辨率。成像时，溴化乙锭采用标准紫外透射仪成像，而SYBR Safe染料可在紫外光（约280 nm）且具有可见光性能的激光扫描仪或蓝光（450-500 nm）下观察。

各种SYBR染料有何区别？

所有SYBR染料都与dsDNA、ssDNA和RNA结合，但敏感性不同。SYBR Green I用于dsDNA和ssDNA染色。SYBR Green II可以对dsDNA和ssDNA进行染色，但对RNA的敏感性更好。SYBR Gold 是在SYBR Green I和II之后开发的，是最敏感的荧光凝胶染色剂。SYBR Safe DNA凝胶染色剂是一种用于蓝光系统的致突变性更低的配方。它不像SYBR Green I和II那么敏感，但可与溴化乙锭相比。 < / p >

Why do I sometimes see speckles in my gel when using SYBR Safe DNA Gel Stain?

Many whitening agents used in clothing, as well as some fungi and bacteria, fluoresce at the same wavelengths as SYBR Safe DNA gel stain. These contaminants within or on the surface of the gel may produce this speckling.

Which direction does the SYBR Safe dye run during electrophoresis?

Similarly to ethidium bromide, SYBR Safe DNA Gel Stain runs in the opposite direction of the migrating DNA. This has no practical effect on the use of gels cast with SYBR Safe DNA Gel Stain, as only the very bottom of the gel will have a lower concentration of stain. This effect can be partially counteracted by staining the gel with SYBR Safe DNA Gel Stain after electrophoresis. Solutions of dye should not be added to the running buffer as this can cause breakdown of the dye at the electrodes and release toxic volatile compounds into the air.

What other excitation wavelengths can I use to visualize SYBR Safe DNA Gel Stain?

SYBR Safe DNA Gel Stain has two main excitation peaks: in the UV region at 280 nm, and in the visible region at 502 nm. Thus, wavelengths from 254 nm to 300 nm UV excitation will work, as will excitation with 488 nm lasers, 470 nm LEDs, and broad blue light sources (such as the Safe Imager Blue-Light Transilluminator (Cat. No. S37102). Maximal excitation occurs at 502 nm; the Safe Imager Blue-Light Transilluminator is therefore the best choice for excitation of SYBR Safe DNA Gel Stain. You can find the full excitation and emission spectra for SYBR Safe DNA Gel Stain online and also in the protocol provided with the stain.

Can I view SYBR Safe DNA gel stain with my ethidium bromide filter and camera settings?

Some ethidium bromide filters allow the transmission of all light above 500 nm. These filters (which are often yellow) and their associated camera settings can be used with SYBR Safe DNA Gel Stain, usually with only minor adjustments to the exposure or gain. Other ethidium bromide filters (often red) only transmit light around or above 600 nm; these filters and their associated camera settings are not suitable for use with SYBR Safe DNA Gel Stain.

Find additional tips, troubleshooting help, and resources within our Nucleic Acid Purification and Analysis Support Center.

Can bands be seen on a UV transilluminator without the use of emission filters?

Bands stained with SYBR Safe DNA Gel Stain are visible to the eye on a 300 nm transilluminator. If a camera is not equipped with a filter, the excitation light will be captured on the image to give a 'washed out' appearance. You can obtain optimum detection by photographing the gel using a UV-compatible emission filter with your CCD or film camera. UV bulbs may also emit some infrared (IR); if your camera lens is not specially coated to block IR, an IR-blocking filter is needed to prevent the appearance of faint images of the UV bulbs behind your gel. For optimum detection and complete safety, use the Safe Imager Blue-Light Transilluminator.

What is the difference between your SYBR Safe Stain and ethidium bromide?

SYBR Safe Stain is non-mutagenic and non-toxic. It shows very similar sensitivity in the UV range, ~500 pg/band, with equivalent resolution to ethidium bromide. For imaging, ethidium bromide is visualized using a standard UV transilluminator, while SYBR Safe stain can be viewed with either UV (~280 nm), laser scanners with visible light capability, or blue light (450 to 500 nm).

Find additional tips, troubleshooting help, and resources within our Nucleic Acid Purification and Analysis Support Center.

What are the differences between all the SYBR dyes?

Different SYBR dyes bind to dsDNA, ssDNA, and RNA, but vary in the sensitivity and specificity with which they bind to different nucleic acids. SYBR Green I Nucleic Acid Gel Stain is used for staining dsDNA and ssDNA. SYBR Green II RNA Gel Stain will stain dsDNA and ssDNA but has better sensitivity for RNA. SYBR Gold Acid Gel Stain was developed after SYBR Green I and II and is the most sensitive fluorescent gel stain offering the highest sensitivity for both DNA and RNA. SYBR Safe DNA Gel Stain is a reduced mutagenicity formula designed for use with blue light systems. It is less sensitive than the SYBR Green I and II but comparable to ethidium bromide.

Does use of SYBR Safe stain affect cloning efficiencies after gel purification?

We have found a distinct advantage to using SYBR Safe stain rather than ethidium bromide when purifying DNA from gels for downstream use. SYBR Safe stain is compatible with blue light imaging systems as well as UV. Using blue light to visualize the DNA allows you to purify a band with virtually no UV-induced nicking or crosslinking. This can dramatically increase cloning efficiency. Data from one such experiment showing higher cloning efficiency with PCR products visualized with SYBR Safe and blue light vs. ethidium bromide and UV light can be seen on the information page for Safe Imager 2.0 Blue-Light Transilluminator (Cat. No. G6600) and on the SYBR Safe home page.

Why do I sometimes see "speckles" in my gel when using SYBR Safe stain?

Many whitening agents used in clothing, some synthetic fibers, as well as some fungi and bacteria, fluoresce at the same wavelength as SYBR Safe stain. These contaminants within or on the surface of the gel may produce this “speckling”. This can be avoided by being careful with preparation of the gel (i.e. try to keep the gel dust free). Alternatively, to obtain a publication quality image you may be able to preferentially photobleach some contaminants by leaving the gel on the UV box for 15-30 minutes, where the speckles will disappear before the SYBR stain photobleaches.

How do I use the SYBR Safe photographic filter?

The SYBR Safe photographic filter (Cat. No. S37100) is a Wratten #9 gelatin filter. This filter is a 75 mm x 75 mm sheet of plastic that should be mounted in front of the lens of the camera. With a Polaroid camera and B&W film (#667), the filter may be taped inside the hood or mounted in a cassette and snapped in place inside the hood (the opening in which the camera lens is mounted upon).

For other camera systems, this sheet may be mounted in a cassette or filter-housing and placed in front of the camera lens. An alternative is to use thread-on glass filters of the same rating available from most camera supply vendors. Please note - not all camera systems require use of the SYBR Safe filter. See the SYBR Safe home page for a list of recommended filters and settings for several different instruments - you can find the page by searching "SYBR Safe DNA Gel Stain" from theThermo Fisher Scientific website home page.

Can DNA bands stained with SYBR Safe be seen on a UV transilluminator without the use of emission filters?

DNA bands stained with SYBR Safe stain may be visible by eye on a 300 nm transilluminator if there is a sufficient amount of DNA per band. However, optimal detection is obtained by photographing the gel using a Wratten #9 emission filter (or other filter with a similar rating) with your CCD or film camera. With UV transilluminators (light boxes), UV bulbs may also emit some infrared (IR) wavelengths; if your camera lens is not specially coated to block IR, an IR-blocking filter is needed to prevent the appearance of the UV bulbs under your gel.
