Given the importance of Arginine metabolic pathway in physio-pathological processes and in particular in immune regulation, we developed and validated a robust and ease-to-use immunoassay for the simultaneous detection and quantification of both Arginine and Ornithine in plasma / sera originating from multiple species (20µL min. sample volume).
