Peptide Mass Fingerprinting (PMF) of tryptically in-gel digested samples is a well-established protein identification technique for MALDI mass spectrometry but an in-depth PMF evaluation for in-gel digestions of less specific enzymes is still missing. This study demonstrates that the MALDI-LTQ-Orbitrap

The success of matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) as a widely employed analytical tool in the biomolecular sciences builds strongly on an effective laser-material interaction that is resulting in a soft co-desorption and ionization of matrix and imbedded biomolecules.

Journal of proteome research, 8(7), 3588-3597 (2009-05-14)
The performance of the recently developed 4-chloro-alpha-cyanocinnamic acid (Cl-CCA) matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) matrix was investigated in comparison to the most widely used matrix alpha-cyano-4-hydroxycinnamic acid (CHCA). For this purpose, in-solution digestions of standard proteins in
