abstract = {Desorption/ionization (DI)-mass spectrometric (MS) methods
offer considerable advantages of rapidity and low-sample
input for the analysis of solid biological matrices such as
tissue sections. The concept of desorption electrospray
ionization (DESI) offers the possibility to ionize compounds
from solid surfaces at atmospheric pressure, without the
addition of organic compounds to initiate desorption.
However, severe drawbacks from former DESI hardware
stability made the development of assays for drug
quantification difficult. In the present study, the
potential of new prototype source setups (High Performance
DESI Sprayer and Heated Transfer Line) for the development
of drug quantification assays in tissue sections was
evaluated. It was demonstrated that following dedicated
optimization, new DESI XS enhancements present promising
options regarding targeted quantitative analyses. As a model
compound for these developments, ulixertinib, an inhibitor
of extracellular signal-regulated kinase (ERK) 1 and 2 was
used.},
