This antibody reacts with the ~160 kDa nNOS protein and does not exhibit any cross-reactivity with the related eNOS or iNOS proteins. During development reactivity was confirmed with a ~160 kD band on western blots of rat and mouse brain tissue lysates (20 µg). For use in immunohistochemistry with paraffin embedded tissues some background staining was evident.
NOS activity requires homodimerization as well as three cosubstrates (L-arginine, NADPH and O2) and five cofactors or prosthetic groups (FAD, FMN, calmodulin, tetrahydrobiopterin and heme). Several distinct NOS isoforms have been described and been shown to represent the products of three distinct genes. These include two constitutive Ca2+/CaM-dependent forms of NOS, including NOS1 (also designated ncNOS) whose activity was first identified in neurons, and NOS3 (also designated ecNOS), first identified in endothelial cells.
