Quite a few labor intensive and time intensive techniques are available for RNA isolation, purification and quantification. Quantification of RNA samples is done by measuring their absorption at 260 nm, although the quality and integrity of RNA samples are frequently based on gel electrophoresis followed by ethidium bromide visualization (one–3).
