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.

Specificity

Clone 2F12 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects endothelial nitric oxide synthase (eNOS). It targets an epitope within 16 amino acids from the Flavodexin-like domain.

Immunogen

KLH-conjugated linear peptide corresponding to 16 amino acids from the Flavodoxin-like domain from the Internal region of human eNOS.

Application

Quality Control Testing

Evaluated by Western Blotting in Rat Spleen tissue lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected eNOS in Rat Spleen tissue lysate.

Tested Applications

Affinity Binding Assay: A representative lot from a representative lot bound eNOS peptides with a KD of 3.3 x 10-8 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected eNOS in human placenta tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected eNOS in HUVEC and HepG2 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-eNOS, clone 2F12 ZooMAb®, Cat. No. ZRB1252, is a recombinant Rabbit monoclonal antibody that specifically targets eNOS and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Nitric oxide synthase, endothelial (UniProt: P29474; also known as EC:1.14.13.39, Constitutive NOS, cNOS, EC-NOS, Endothelial NOS, eNOS, NOS type III, NOSIII) is encoded by the NOS3 gene (Gene ID: 4846) 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 eNOS is mainly expressed in vascular endothelial cells and cardiomyocytes. The NO produced by the eNOS in endothelial cells acts as a vasodilator and regulates blood flow and blood pressure. In cardiac cells, eNOS is expressed in response to shear stress, exercise, chronic hypoxia, and cardiac failure. In endothelial cells, eNOS is localized in specialized plasmalemmal pockets known as caveolae, which contain a scaffolding protein termed caveolin. Acylation of eNOS by either myristate or palmitate targets it to caveolae, which facilitates enzyme activation following receptor stimulation. In a resting cell, eNOS is inhibited by its interaction with caveolin. Following agonist activation, eNOS dissociates from caveolin and translocates to the cytosol. The eNOS is generally activated in response to an increase in intracellular Ca2+ following stimulation with receptor-dependent agonists such as acetylcholine. However, shear stress can also activate this enzyme, independently of Ca2+ level changes, via a tyrosine kinase-dependent mechanism involving its phosphorylation and redistribution. Low concentrations of NO in the endothelial cells prevent their apoptotic death and maintain their integrity during inflammation and atherosclerosis. Distorted production of NO in endothelial cells has been linked to hypertension, hypercholesterolemia, diabetes, and even cardiac failure. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
