Western Blot Troubleshooting | Thermo Fisher Scientific - CN
Most of the nonionic detergents (e.g., Triton X-100, NP-40, and Tween 20 detergents) interfere with SDS- polyacrylamide gel electrophoresis (SDS-PAGE). Keep the ratio of SDS to nonionic detergent at 10:1 or greater to minimize these effects.
This system provides fine resolution for RNA molecules less than 600 nt [28]. In our laboratory, we use 15% polyacrylamide/8 M urea denaturing gel, which can separate molecules from 25 to 150 bp [29].

- What is polyacrylamide gel electrophoresis (PAGE)?
- Polyacrylamide gel electrophoresis (PAGE) is a quick and sensitive method for analyzing the composition of mixtures of proteins. Since the early 1970s, this method has become a routine and frequently used analytical procedure in all protein chemistry laboratories, and as such, biology students should of course be familiar with this basic technique.
- How does a polyacrylamide gel separate analytes?
- The basic principle of PAGE is to separate analytes by passing them through the pores of a polyacrylamide gel using an electric current. To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS).
- How does polyacrylamide gel form?
- The polyacrylamide gel forms by polymerizing acrylamide and a crosslinking agent, i.e., N, N’-methylene-bis-acrylamide. It does not react with proteins and consists of pores and channels that allow the protein to move through it.
- What determines a molecule's charge in a polyacrylamide gel?
- In PAGE, this is determined by the charge, size (molecular weight) and shape of the molecule. Analytes move through pores formed in polyacrylamide gel. Unlike DNA and RNA, proteins vary in charge according to the amino acids incorporated, which can influence how they run.
