Analysis of Oligonucleotides by Electrospray Ionization Mass Spectrometry [PDF]
Current Protocols in Nucleic Acid Chemistry, 2000 AbstractBecause of the high molecular weights and thermal lability of biomolecules such as nucleic acids and protein, they can be difficult to analyze by mass spectrometry. Such analyses require a “soft” ionization method that is capable of generating intact molecular ions.
