Utility of a new parameter—the ratio of immunoreactive ACE protein (with mAb 9B9) to ACE activity. Plasma samples from 100 pulmonary patients were analyzed for ACE activity using ZPHL substrate, with results displayed in ascending order (A). The ratio of ACE immunoreactive protein (with mAb 9B9) to ACE activity was then calculated (B), identifying the likely presence of non-endothelial-derived ACE in some plasma samples (yellow bars)
