  • What is polyacrylamide gel electrophoresis (PAGE)?
  • Preparative polyacrylamide gel electrophoresis (PAGE) is a powerful tool for purifying RNA samples. Denaturing PAGE allows separation of nucleic acids that differ by a single nucleotide in length.
  • How is RNA extracted from a polyacrylamide gel?
  • Overview RNA will be extracted from the gel using the ‘crush and soak’ method (see also Purification of DNA Oligos by Denaturing Polyacrylamide Gel Electrophoresis (PAGE)). 8.2. Duration
  • What are the elution conditions for a polyacrylamide gel?
  • The elution conditions can vary greatly depending on the electroelution apparatus, the acrylamide percentage of the gel, the membranes, and the buffer used. A good starting point is to conduct the electrophoresis in 1× TBE at 100V for 2h. This should be sufficient to elute ~100 nucleotide long RNA molecules from a 4% polyacrylamide gel.
  • How does polyacrylamide gel work?
  • The polyacrylamide gel is cast between two glass plates that are separated by two thin Teflon or nylon spacers. A so-called shark's tooth comb or, less frequently, a standard slotted comb forms the sample wells into which the RNA samples are loaded before electrophoresis.
