We produced a monoclonal antibody (mAb) against N(G),N(G)-dimethyl-L-arginine (asymmetric dimethylarginine: ADMA), an endogenous competitive inhibitor of nitric oxide synthase (NOS), and developed an enzyme-linked immunosorbent assay (ELISA). The competitive ELISA method using the mAb determined 5 nM-100 nM ADMA, and ADMA levels in human plasma and urine were found to be 0.78 µM and 51.3 µmol/g of creatinine respectively.
