Oligodeoxynucleotides which contain 7-deaza analogues of the normal purine nucleotides have been synthesized both enzymatically and chemically. When subjected to matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis, the modified samples offer both higher stability and increased sensitivity compared to otherwise identical unmodified oligodeoxynucleotides. In view of these observations, models for the fragmentation of oligodeoxynucleotides in MALDI-MS with positive ion detection mode are presented. Additionally, the potential use of 7-deaza purine nucleotides in the MALDI-MS analysis of DNA sequencing reactions is discussed.
