Mass Spectrometry Assay for Plasma-Renin

摘要

Provided are methods for measuring renin activity in a plasma sample using mass spectrometry. The methods generally involve ionizing purified angiotensin 1 from the sample and detecting the amount of angiotensin 1 ions generated. The amount of detected angiotensin 1 ions are then related to the amount of angiotensin 1 generated in the sample, which in turn is related to renin activity in the sample.
