Abstract
Provided herein are methods for determining a concentration of RNA (e.g. mRNA) in a solution. Certain aspects of the disclosure relate to digesting the target RNA polymer by adding a base to a solution of RNA, optionally comprising at least one chemically modified nucleotide, and incubating the mixture to digest the RNA into a plurality of nucleotides. Certain other aspects of the disclosure relate to measuring the absorbance of the digested RNA mixture at 260 nm; while other aspects relate to using the absorbance measurement with a value of a relative percent of each nucleotide in the digestion mixture, and a mass-corrected coefficient of each nucleotide in the mixture to determine a concentration of the RNA. Other aspects of the disclosure relate to measuring the concentration of RNA in a solution using computer-implemented techniques.
