Maximized Spatial Information and Minimized Acquisition Time of Top-Hat IR-MALDESI-MSI of Zebrafish Using Nested Regions of Interest (nROIs)
Joignant, A. N., Ritter, M. M., Knizner, K. T., Garrard, K. P., Kullman, S. W., & Muddiman, D. C. (2023, August 1). JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY, Vol. 8.
author keywords: IR-MALDESI; mass spectrometry imaging; spatialresolution; nested region of interest; zebrafish
TL;DR:
The nROI method was characterized on mouse liver and applied to top-hat MSI of zebrafish using a novel optical train, which resulted in a significant improvement in both acquisition time and spatial detail of the zebra fish.
