L-Ng-monomethyl arginine citrate

L-NMMA is a relatively non-selective inhibitor of all NOS isoforms. It is the archetypal NOS inhibitor to which other inhibitors are most often compared.1 The Ki values for nNOS (rat), eNOS (human), and iNOS (mouse) are approximately 0.18, 0.4, and 6 µM, respectively.2,3WARNING This product is not for human or veterinary use.
