RNA samples are notoriously difficult to work with given their highly labile nature and tendency to degrade even under carefully controlled RNase-free conditions and maintenance in cold environments. Exposure to slightly elevated temperatures for even short time periods can compromise RNA integrity and detrimentally affect downstream assays and results.
