NOS1 Inhibitors

Santa Cruz Biotechnology now offers a broad range of NOS1 Inhibitors. Nitric oxide (NO) has a broad range of biological activities including cell signaling pathways in phylogenetically diverse species. Nitric oxide synthases (NOSs), the enzymes responsible for synthesis of NO, contain an N-terminal oxygenase domain and a C-terminal reductase domain. NOS1 (also designated ncNOS) is a constitutive Ca2+/CaM-dependent form of NOS, whose activity was first identified in neurons. NOS1 Inhibitors offered by Santa Cruz inhibit NOS1 and, in some cases, other cell signaling and nitric oxide synthesis related proteins. View detailed NOS1 Inhibitor specifications, including NOS1 Inhibitor CAS number, molecular weight, molecular formula and chemical structure, by clicking on the product name.
