  • What is 8 M urea/TBE polyacrylamide gel used for?
  • The gel recipe and protocol presented here for 8 m urea/TBE polyacrylamide gels can be used for a variety of applications including mapping RNA with nuclease S1, ribonuclease protection assay, or analysis of RNA by primer extension.
  • 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.
  • What is a 15% gel used for?
  • These 15% gels are optimized for the analysis and purification of products ranging from 10–40 bases, making them an ideal choice for synthetic oligo analysis and purification, RNase Protection Assays (RPA), in vitro transcription studies, and northern blot analysis.
  • What is the working strength of TBE in polyacrylamide gel electrophoresis?
  • TBE is used at a working strength of 1× for polyacrylamide gel electrophoresis. This 1× concentration is twice the strength usually used for agarose gel electrophoresis.
