| Abstract |
Cardiac fibrosis is characterized by excessive deposition of extracellular matrix (ECM) and is a common complication of various cardiovascular diseases. However, little is known about proteins in the cardiac extracellular space. Proteomics analysis of cardiac ECM can be challenging due to the presence of more abundant intracellular proteins, the low degree of solubility of integral ECM proteins, and the presence of abundant posttranslational modifications. Here we describe an extraction methodology based on tissue decellularization, which allows the biochemical subfractionation of extracellular proteins in cardiac tissue. These relatively low-complexity protein fractions are suitable for analysis by gel-LC-MS/MS and other proteomics techniques. |
