Abstract
A method for quantifying mRNA capping efficiency includes combining a sample, an enzyme mixture, and an isotopic standard solution in a buffer solution to create an incubation mixture, the enzyme mixture including a non-specific, single-stranded nuclease and an acid phosphatase and the isotopic standard including isotopically labeled m7G and isotopically labeled 2'-O-methylated nucleoside; incubating the mixture; and analyzing the mixture using liquid chromatography-mass spectrometry to determine at least one of a capping efficiency and a 2-O-methyltransferase efficiency.
