We evaluated the cathepsin A activity of a parietal thrombus of an abdominal aortic aneurysm. We compared this activity to that of a retracted blood clot homogenate. Cathepsin A of aneurysm parietal thrombus homogenate and blood clot homogenate showed the highest activity on Z-Phe-Ala. It was lower on Z-Phe-Phe, Z-Glu-Tyr, Z-Glu-Phe, Z-Gly-Phe, and the lowest activity was on Z-Gly-Ala. We conclude that cathepsin A's activity on a parietal thrombus of an aneurysm is much higher than blood clot cathepsin A activity.
