MOESM2 of Combining patient proteomics and in vitro cardiomyocyte phenotype testing to identify potential mediators of heart failure with preserved ejection fraction

Additional file 2: Figure S2. Microscopy for Platelet Purity. Isolated platelets were observed under the microscope. Visible red blood cells and leukocytes were counted and calculated as a percentage of platelets in each field. Microscopy confirmation verified that the purified platelet had a leukocyte contamination < 0.02 % and a red blood cell contamination of < 1 %.
