RNASE H-BASED RNA PROFILING

摘要

Methods for determining the presence, absence and/or amount and/or identity of RNA in a biological or other sample employs capturing and separating a DNA:RNA hybrid formed by a DNA probe and the RNA of interest from unhybridized DNA and RNA with an RNase H under conditions wherein the nuclease activity of the RNase H is inhibited, releasing the DNA probe by altering the conditions so that the nuclease activity is restored, and determining the presence or amount, and, for multiplex samples, nature of the DNA released. The method can be used to determine RNA of various types, including RNA comprising transcriptomes.
