Notes:
The keV Cs+ liquid secondary-ion mass spectrometry (LSIMS) and 252Cf-plasma desorption (PD) mass spectra of recombinant proteins in the 10-25 kDa mass range are compared. Both techniques showed comparable mass accuracy and sensitivity, and in the case of LSIMS, remarkably short analysis time. Analysis by the PD/nitrocellulose method demonstrated slightly higher sensitivity and relativity lower dependence on the salt and buffer content of the protein sample.
