What is polyacrylamide gel electrophoresis?

Polyacrylamide gel electrophoresis (PAGE) is a powerful tool for analyzing RNA samples. Denaturing PAGE provides information on the sample composition and structural integrity of the individual RNA species. Nondenaturing gel electrophoresis allows separation of the conformers and alternatively folded RNA species.

What is nondenaturing gel electrophoresis?

Nondenaturing gel electrophoresis allows separation of the conformers and alternatively folded RNA species. It also can be used to resolve RNA protein complexes and to detect RNA complex formation by analyzing changes in the electrophoretic mobility of the RNA.

Are electroeluters effective and recover comparable amounts of purified RNA?

Our results show that both electroeluters are effective and recover comparable amounts of purified RNA. Keywords: Electroelution; Electrophoresis; Gel elution; PAGE; Polyacrylamide; RNA purification. Copyright © 2021 Elsevier Inc. All rights reserved.

Can electroeluters recover RNA from gel pieces?

Here, we have compared two electroeluters with different chamber designs for their ability to recover RNA from gel pieces. Our results show that both electroeluters are effective and recover comparable amounts of purified RNA. Keywords: Electroelution; Electrophoresis; Gel elution; PAGE; Polyacrylamide; RNA purification.

How do you purify RNA from a polyacrylamide gel?

One common purification method involves slicing a section of a polyacrylamide gel containing the RNA of interest and eluting the RNA out of the gel using electroelution. Various electroeluter models are available but sometimes a given model becomes discontinued, compelling researchers to choose a different model.

What is the difference between agarose gel and polyacrylamide gel?

In contrast to electrophoresis using agarose gels, which occurs while the gel is horizontal, polyacrylamide gels are run while in the vertical position. Gels are also typically run at 45°C–55°C, which is the melting temperature of RNA, and in the presence of 6–8 m urea.
