Discovery of a solvent effect preventing quantitative profiling by matrix-assisted laser desorption/ionization and its treatment

摘要

RATIONALE: In analyte profiling by matrix-assisted laser desorption/ionization (MALDI), drawing a quantitative profile map is an outstanding problem. Recently, we developed a method to quantify an analyte by MALDI, which is needed to solve the problem. Another requirement for quantitative profiling is the quantitative sample-to-matrix analyte transfer, which is investigated in this work.
