Cross-validation of Homoarginine ELISA and LC/MS data in human plasma samples
hArg was quantified in human plasma samples from 40 healthy subjects either using IS-I-0500 ELISA kit or by liquid chromatography–mass spectrometry (LC/MS). Correlation coefficient of 0.964 confirms the accuracy of the immunoassay.
HomoArginine ELISA kitRef: IS-I-0500
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.
