Carl Novina with a sequencing gel. A sequencing gel is used to separate small RNA species. After high voltage separation in the sequencing gel, the small RNAs are transferred to a cellulose membrane and detected with radioisotopes - labeled RNAs. This procedure is a specialized adaptation of traditional Northern blotting caled modified Northern blotting.
