In situ tissue analysis of metabolites, lipids, and proteins in the gill glands of Bloodfin Tetra by LAESI Mass Spectrometry

摘要

Detection of diverse of molecular classes by direct analysis of unprocessed tissue using LAESI-MS demonstrates its potential for the simultaneous detection of small metabolites, lipids and peptides/proteins from biological samples. A unique protein that was found only in the mature male gill glands using rapid screening by LAESI-MS can be related to the function of this modified organ.
