UV-MALDI-MS analysis of non-covalent complexes with a 6-aza-2-thiothymine-matrix: effect of wavelength and fluence on the detection of the complexes

摘要

For non-covalent peptide/peptide complexes optimal MALDI conditions are found if the ATT matrix is excited at wavelengths of low matrix absorptivity. Therefore overall data provide important hints on how MALDI mass spectrometry of non-covalent complexes can be optimized.
