Modified bases characterized in intact DNA by mass-analyzed ion kinetic energy spectrometry.

A E Schoen, R G Cooks, J L Wiebers.   

Abstract

Pyrolysis of DNA into a chemical ionization source yields protonated bases and other base-containing ions. Kinetic energy spectra allow the characterization of the bases 5-methylcytosine and 1-methyladenine from underivatized salmon sperm DNA. Isomeric bases are distinguishable with this technique.
