HomoArginine (hArg) is a basic non-essential amino acid that exerts beneficial effects on vascular homeostasis, more likely through the increase of nitric oxide (NO) that can be explained through two mechanisms since hArg i) serves as a precursor of NO and ii) favors the elevation of L-Arg – main substrate of NO synthase – by inhibiting the enzyme Arginase.
The homoArginine (hArg) ELISA kit allows for the determination of hArg in serum and plasma samples working with a sample volume of 20μL. The kit is easy to implement and well suited for both preclinical and clinical studies.
