Desorption Electrospray Ionization-Mass Spectrometry of Proteins [PDF]

open access: yesAnalytical Chemistry, 2007
Desorption electrospray ionization-mass spectrometry (DESI-MS) was evaluated for the detection of proteins ranging in molecular mass from 12 to 66 kDa. Proteins were uniformly deposited on a solid surface without pretreatment and analyzed with a DESI source coupled to a quadrupole ion trap mass spectrometer.
