ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.


Clone 1F14 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects neuronal nitric oxide synthase (NOS1).


His-tagged recombinant fragment corresponding to the first 300 amino acids from the N-terminal region of human NOS1.

Target description

Nitric oxide synthase, brain (UniProt: P29475; also known as EC:, Constitutive NOS, NC-NOS, NOS type I, Neuronal NOS, N-NOS, nNOS, Peptidyl-cysteine S-nitrosylase NOS1, bNOS) is encoded by the NOS1 gene (Gene ID: 4842) in human. NOS is known to exist in three forms (a) a soluble, constitutively expressed enzyme found in high concentrations in the brain (nNOS or NOS-1), (b) a constitutively expressed endothelial membrane bound enzyme (eNOS, NOS-3), and (c) an inducible enzyme (iNOS or NOS-2) that is associated with the cytotoxic function of macrophages. They exhibit similarities in their structure and mechanism of action. Calmodulin is required for the activity of all three isoforms. All NOS are single polypeptides that differ in their rates of Nitric oxide ( NO), Ca2+- dependence, cytochrome c reduction, and NADPH utilization. For their catalytic activities NOS isoforms require three distinct domains: (a) a reductase domain, (b) a calmodulin-binding domain, and (c) an oxygenase domain. The reductase domain contains the FAD and FMN moieties. The oxygenase domain catalyzes the conversion of L-arginine to citrulline and NO. The nNOS is a peripheral membrane protein that is expressed in the nervous tissue and in skeletal muscle. The functionality of nNOS requires a rapid, localized production of NO and a timely end of its biosynthesis. Its primary regulation is mediated through the obligatory binding of calmodulin, which occurs in response to transient increases in intracellular Ca2+. The binding of calmodulin to nNOS triggers the transfer of NADPH derived electrons from the reductase domain to the oxygenase domain, which initiates the catalytic activity of the enzyme. The N-terminal region of nNOS also has a unique binding site for a highly conserved protein called PIN (protein inhibitor of NOS) that inhibits catalytic activity by destabilizing homodimer formation. The binding of PIN occurs at amino acids 163 - 245 of nNOS. When nNOS is phosphorylated by CaM kinase, the interaction between PIN and nNOS is disrupted. CaM kinase may potentially augment NOS activity by blocking PIN repression of nNOS. Improper regulation of nNOS has been implicated in several neurologic diseases including neurodegenerative diseases such as Huntington s disease and Parkinson s disease. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
