Method development for the detection and quantification of dm5C and rm5C by LC-MS/MS. (A) Elution profiles of DNA oligonucleotide hydrolysate, spiked with S. cerevisiae RNA SIL-IS and [D3]dm5C monitored by UV-absorption and mass chromatograms from LC- MS/MS. (B) Shows the elution profiles of a hydrolyzed RNA sample, spiked with both internal standards as well as the corresponding MS/MS data. (A and B) show distinct contamination of the samples with the matching m5C derivative.
