毒害物质数据 | 1239-45-8(Hazardous Substances Data) |
毒性 | Intercalating dye widely used to stain DNA in gels and gradients. The DNA can be visualized readily by irradiation with ultraviolet light, as little as 0.5 μg of DNA being detectable by such methods. Ethidium bromide is also added to cesium chloride density gradients, since as an intercalating molecule it binds more readily to linear DNA than to closed collinear circles of DNA (such as plasmids). Binding of ethidium bromide reduces the density of DNA, thus covalent circles of DNA have higher densities at saturating concentrations of ethidium bromide, permitting the separation of plasmid DNA. Ethidium bromide is a putative carcinogen. |

常见问题列表
荧光分析法可分为直接测定法和间接测定法二种。直接测定法是利用物质自身发射的荧光,即所谓“自荧光”或“内源荧光”来进行测定。但在自然界中只有少部分物质在光激发后可以发射荧光,而有相当一部分物质发荧光很弱或不发射荧光,如蛋白和核酸就是发荧光很弱的物质。为了充分利用荧光分析法灵敏度高这一特点就需使其转化成荧光物质再进行测定。此时可用某些试剂(如荧光染料) 使其与荧光较弱或不显荧光的物质共价或非共价结合,以形成发荧光的结合物再进行测定,这就是所谓的“荧光探针”技术或“荧光标记”技术。使试剂(荧光剂) 吸附在大分子上或共价结合到大分子上。所用的染料溴化乙啶被叫做“荧光探剂”。探剂荧光特性的变化,实际上是由于大分子构象的变化所引起的探剂环境变化的信号,所以利用这种信号还可以得到大分子构象变化的信息。
Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
The preparation of agarose gel:
1. Agarose gels are commonly used in concentrations of 0.5% to 2.5% depending on the size of bands needed to be separated.
2. Mix the agarose powder with 1X TAE/TBE.
3. Microwave for 1-3 min until the agarose is completely dissolved (
Caution
: not overboil).
4. Make the solution cool down before solidification.
5. Add ethidium bromide (EtBr) to a final concentration of approximately 0.2-0.5 μg/mL (Stocks are generally 10 mg/ml, and require 5 µL stock/100 mL gel).
6. Ethidium bromide binds to the DNA and you could visualize the DNA under ultraviolet (UV) light.
CAUTION: EtBr is a known mutagen. Please pay attention to strengthening protection.
