Abstract
Human tissues and organs can be preserved intact by fixation with formalin for the future analysis of biomolecules of
interest. With the advances in high-throughput methods, numerous protocols have been developed and optimized to attain the
most pathophysiological information out of biomolecules, including RNA and proteins, in formalin-fixed samples. However,
there is no systematic study to examine the effects of formalin fixation on the lipidome of biological samples in a global fashion.
In this study, we conducted a mass spectrometry-based analysis to survey the alteration in the lipidome of mice brains by fixation
methods. A total of 308 lipids were quantitatively measured using triple quadrupole mass spectrometry. We found that most were
unchanged after formalin fixation except for a few lipid classes such as phosphatidylethanolamine.
