Specific sequences in RNA preparations can be detected by blotting and hybridization analysis using techniques very similar to those originally developed for DNA. Fractionated RNA is transferred from an agarose gel to a membrane support (northern blotting), while unfractionated RNA is immobilized by slot or dot blotting. The resulting blots are studied by hybridization analysis with labeled DNA or RNA probes. Included in this unit are detailed procedures for RNA denaturation, blotting and hybridization. Also described is a method for stripped hybridization probes from blots so the blots can be re-hybridized with a different probe.
