Protocols
  • Denaturing and Non-denaturing Agarose Gel Electrophoresis of RNA (Ambion)
    The overall quality of an RNA preparation may be assessed by electrophoresis on a denaturing agarose gel; this will also give some information about RNA yield. A denaturing gel system is suggested because most RNA forms extensive secondary structure via intramolecular base pairing, and this prevents it from migrating strictly according to its size. This protocol provides procedures for performing both non-native and native agarose gel electrophoresis of RNA

  • RNA quality control (FlyChip)
    Any extracted RNA must be devoid of contaminants such as salt, protein, solvents and genomic DNA. Poor quality RNA will lead to problems when performing the reverse transcription and labelling and might affect data quality. We quality control our extracted RNA using gel electrophoresis and optical density measurements. Gel electrophoresis is used to check for Genomic DNA contamination and RNA decay. Optical density is used to assay the RNA yield and to check for contamination by salt, solvent, protein, etc.
