ABSTRACT:
RNA such as messenger RNA is digested to nucleotide phosphates including AMP or ADP. The ATP or a byproduct of the phosphorylation, e.g., pyruvate, is detected. Exemplary enzymes used (with appropriate co-reactants and co-factors) are: (1) polynucleotide phosphorylase, pyruvate kinase and luciferase, or (2) phosphodiesterase (or RNase), myokinase, pyruvate kinase and luciferase. The phosphorylation to ATP (e.g., with pyruvate kinase) is preferably coupled with the previous (reversible) enzymatic step.
