Phosphorylation of cardiac myofilament proteins represents one of the main post-translational mechanisms that regulate cardiac pump function. Human studies are often limited by the amount of available tissue as biopsies taken during cardiac catheterization weigh only 1 mg (dry weight). Similarly, investigation of time- (or dose-) dependent changes in protein phosphorylation in animal studies is often hampered by tissue availability. The present study describes quantitative analysis of phosphorylation status of multiple myofilament proteins by 2-DE and Pro-Q® Diamond stained gradient gels using minor amounts (˜0.5 mg dry weight) of human and pig cardiac tissue.
