LABEL-FREE ANALYSIS OF RNA CAPPING EFFICIENCY USING RNASE H, PROBES AND LIQUID CHROMATOGRAPHY/MASS SPECTROMETRY

Abstract:

Methods to qualitatively and quantitatively determine mRNA capping, and to determine 5' capping efficiency and 5' cap identity in RNA samples, all without the need for radiolabels, by using tagged probes that are complementary to the 5' end of target RNA and RNAse H to cleave the 5' end of RNA, then using LC-MS to determine the 5' RNA products.
