Section 3Maintaining an RNase-Free EnvironmentTo avoid introducing RNases, great care must be taken in handling the reagents and purified RNA samples.

Solutions that are prepared by the user should be treated withDEPC to inactivate RNases. See instructions below on how to prepare DEPC-treated solutio
