Combining Gel Retardation and Footprinting to Determine Protein-DNA Interactions of Specific and/or Less Stable Complexes

[Abstract]  

DNA footprinting is a classic technique to investigate protein-DNA interactions. However, traditional footprinting protocols can be unsuccessful or difficult to interpret if the binding of the protein to the DNA is weak, the protein has a fast off-rate, or if several different protein-DNA complexes are formed. Our protocol differs from traditional footprinting protocols, because it provides a method to isolate the protein-DNA complex from a native gel after treatment with the footprinting agent, thus removing the bound DNA from the free DNA or other protein-DNA complexes. The DNA is then

[摘要]  [摘要] DNA足迹是研究蛋白质-DNA相互作用的经典技术。但是,如果蛋白质与DNA的结合较弱,蛋白质的脱落速率较快,或者形成了几种不同的蛋白质-DNA复合物,则传统的足迹方案可能会失败或难以解释。我们的协议不同于传统的足迹协议,因为它提供了一种在使用足迹剂处理后从天然凝胶中分离蛋白质-DNA复合物的方法,从而从游离DNA或其他蛋白质-DNA复合物中去除了结合的DNA。然后从分离的复合物中提取DNA,然后在测序凝胶上电泳以确定印迹模式。该分析为无法使用传统足迹法确定蛋白质与DNA接触的人提供了可能的解决方案。

[背景]核酸酶/化学足迹是一个典型的方法来探测蛋白质-DNA相互作用(腊士和施米茨,1978;萨瑟-德怀特和Gralla,1989;汉普等人,2007) ...

[Abstract]  Construction of chimaeric MVA is a useful tool with which to study gene function of related viruses. The protocol given here describes MVA chimaeras containing genes from Fowlpox virus (FWPV), although this can be applied to DNA derived from other organisms. There are a number of steps required to make the chimaeric MVA: 1) Purification of viral particles; 2) Extraction of DNA from purified viral particles; 3) Assembly of linear recombination templates; 4) Transfection of linear recombination templates; 5) Selection of chimaeric MVA.
Note: This procedure uses live virus, and should be ...
[摘要]  嵌合MVA的构建是研究相关病毒的基因功能的有用工具。 本文给出的方案描述了含有来自鸡痘病毒(FWPV)的基因的MVA嵌合体,尽管这可以应用于来自其他生物体的DNA。 制备嵌合MVA需要许多步骤:1)病毒颗粒的纯化; 2)从纯化的病毒颗粒中提取DNA; 3)装配线性重组模板; 4)线性重组模板的转染; 5)嵌合MVA的选择。
注意:此程序使用活病毒,并应根据国际和国家生物承诺要求使用良好微生物实践进行。 该程序还涉及微生物的遗传修饰,并且在开始前应获得适当的安全批准。
