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.

Electrospray ionization mass spectrometry fingerprinting of propolis [PDF]
The Analyst, 2004 Crude ethanolic extracts of propolis, a natural resin, have been directly analysed using electrospray ionization mass (ESI-MS) and tandem mass spectrometry (ESI-MS/MS) in the negative ion mode. European, North American and African samples have been analyzed, but emphasis has been given to Brazilian propolis which displays diverse and region-dependent ...
