Klaus Faserl et al.
Methods (San Diego, Calif.), 184, 125-134 (2020-02-06)
The analysis, identification and quantification of histones and their post-translational modifications plays a central role in chromatin research and in studying epigenetic regulations during physiological processes. In the last decade analytical strategies based on mass spectrometry have been greatly improved
Risto Kostiainen et al.
Journal of chromatography. A, 1216(4), 685-699 (2008-09-19)
The most widely used ionization techniques in liquid chromatography-mass spectrometry (LC-MS) are electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI). All three provide user friendly coupling of LC to MS. Achieving optimal LC-MS conditions is
