K. Burgess et al., MALDI AND FAB MASS-SPECTROMETRY OF NUCLEOSIDE TRIPHOSPHATES - A COMPARATIVE-STUDY, Nucleosides & nucleotides, 15(11-12), 1996, pp. 1719-1723
Comparison of MALDI and FAB mass spectra of dATP, dTTP, dCTP, and dGTP
shows that the former technique gives clear molecular ions with minim
al fragmentation whereas the latter gives more fragment ions and weake
r parent peaks.
