ASSAY FOR MEASURING ASYMMETRIC METHYLARGININE IN A BIOLOGICAL SAMPLE

摘要

The invention relates to a method of determining the presence and/or amount of an asymmetric methylarginine in a sample, the method comprising: (a) contacting the sample with a nitric oxide synthase (NOS) polypeptide in the presence of a detectably labelled species under conditions which permit the asymmetric methylarginine and detectably labelled species to bind to the NOS polypeptide; and (b) determining the amount or presence of the detectably labelled species bound to the NOS polypeptide.
