Transmission geometry negative ion LSI mass spectra of 10 μm thick mouse brain tissue sections using 2,5-DHAP as a matrix and solvent-free sample preparation at (A) 450°C, (B) 400°C, and (C) 350°C ion transfer capillary temperatures. Each spectrum represents a single laser pulse. Mass spectra from similar mouse brain regions are displayed for comparison.
