  • How do I prepare a denaturing polyacrylamide gel?
  • 2. Prepare a denaturing polyacrylamide gel as described in Polyacrylamide Gel Electrophoresis of RNA (Rio et al. 2010). Set up the gel in the gel box, add TBE electrophoresis buffer (diluted to 1×) to the upper and lower reservoirs, and prerun the gel for 15–45 min at a maximum of 1500 V/45 mA.
  • What is a thin polyacrylamide urea gel?
  • Thin (0.4–1.5 mm) polyacrylamide-urea gels provide high resolution of RNAs up to 1000 nt in size and are capable of resolving single-stranded fragments of RNA that differ in length by as little as 1 nt. The polyacrylamide gel is cast between two glass plates that are separated by two thin Teflon or nylon spacers.
  • When is denaturing gel electrophoresis useful for RNA purification?
  • It is useful for labeled or unlabeled RNAs when sufficient mass is present. It can also be used to isolate small RNAs. In general, RNA purification by denaturing gel electrophoresis is practical only when the size of the desired RNA is 600 nucleotides or less.
  • What is polyacrylamide gel electrophoresis?
  • Electrophoretic mobility is a function of the length, conformation, and charge of the molecule. Polyacrylamide gel electrophoresis is a powerful tool used to analyze RNA samples. When polyacrylamide gel is denatured after electrophoresis, it provides information on the sample composition of the RNA species.
