Significant progress has been made for tissue imaging of proteins using
matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI
IMS). These advancements now facilitate mapping of a wide range of proteins,
peptides, and post-translational modifications in a wide variety of tissues;
however, the use of MALDI IMS to detect proteins from cardiac tissue is limited.
This review discusses the most recent advances in protein imaging and
demonstrates application to cardiac tissue, including the heart valve. Protein
imaging by MALDI IMS allows multiplexed histological mapping of proteins and
protein components that are inaccessible by antibodies and should be considered
an important tool for basic and clinical cardiovascular research. This article is
part of a Special Issue entitled: MALDI Imaging, edited by Dr. Corinna Henkel and
Prof. Peter Hoffmann.
