Denaturing Urea Polyacrylamide Gel Electrophoresis (Urea PAGE)
Urea PAGE or denaturing urea polyacrylamide gel electrophoresis employs 6-8 M urea, which denatures secondary DNA or RNA structures and is used for their separation in a polyacrylamide gel matrix based on the molecular weight.

技术 | 一文读懂聚丙烯酰胺凝胶电泳(PAGE) - 知乎专栏
PAGE是一种技术,根据蛋白质等大分子的电泳迁移率(即分析物向相反电荷的电极移动的能力)来分离它们。 在PAGE中,这由分子的电荷、大小(分子量)和形状决定,分析物通过聚丙烯酰胺凝胶中形成的孔隙移动。 与DNA和RNA不同的是,蛋白质的电荷根据所加入的氨基酸而不同,这可能影响它们的运行方式。 氨基酸串也可能形成二级结构,影响它们的表面大小,从而影响它们如何通过孔隙移动。 因此,如果需要更准确地估计蛋白质的大小,有时最好在电泳前将其 …
denaturing PAGE. 1.

Vigorously agitate the solution by magnetic stirring to ensure complete mixing and solving of UREA powder. 3.
What is the difference between Urea PAGE & SDS PAGE?
Basically, Urea PAGE is for separating DNA or RNA. Urea acts as a strong denaturating agent and prevents the formation of secondary structure in RNA and DNA molecules and make them...

Denaturing Urea Polyacrylamide Gel Electrophoresis (Urea PAGE)
2009年10月29日 · Denaturing urea polyacrylamide gel electrophoresis is used to separate single-stranded DNA or RNA up to a limit of 500 nucleotides. Urea in combination with heat denatures samples and unstructured single strands migrate within the gel matrix according to …
变性尿素聚丙烯酰胺凝胶电泳(尿素PAGE),Journal of Visualized …
尿素page或变性尿素聚丙烯酰胺凝胶电泳采用6-8 m尿素,它可使二级dna或rna结构变性,并用于基于分子量在聚丙烯酰胺凝胶基质中进行分离。 可以使用此方法(1)分离2至500个碱基之间的片段,长度差异小至单个核苷酸。
Prepare denaturing polyacrylamide gel solution. Use Gibco/BRL apparatus. Use 40% acrylamide stock for DNA/RNA gels. Do not use 30% stock for SDS-PAGE gels. Mix in 50 ml beaker. Heat gently in microwave (~ 15 seconds) to dissolve urea. Syringe filter (0.45 μm) gel mix into sidearm flask and degas for 5-10 minutes.
