PA3-031A detects endothelial Nitric Oxide Synthase (eNOS) from canine, bovine, human, mouse and rat tissues. This antibody does not detect brain NOS (bNOS) or inducible NOS (iNOS).
PA3-031A has been successfully used in Western blot, immunohistochemistry, immunofluorescence, and immunocytochemistry procedures. By Western blot, this antibody detects an approximately 140 kDa band representing eNOS from canine cardiac extracts. Immunohistochemical staining of eNOS in mouse cardiac tissue with PA3-031 results in the staining of the endothelium.
The PA3-031A immunogen is a synthetic peptide corresponding to residues P(599) Y N S S P R P E Q H K S Y K(613) C of bovine eNOS.
Nitric oxide (NO) is an inorganic, gaseous free radical that carries a variety of messages between cells. Vasorelaxation, neurotransmission and cytotoxicity can all be potentiated through cellular response to NO. NO production is mediated by members of the nitric oxide synthase (NOS) family. NOS catalyzes the oxidization of L-arginine to produce L-citrulline and NO. Two constitutive isoforms, brain or neuronal NOS (b or nNOS, type I) and endothelial cell NOS (eNOS, type III), and one inducible isoform (iNOS, type II), have been cloned. All NOS isoforms contain calmodulin, nicotinamide adenine dinucleotide phosphate (NADPH), flavin adenine dinucleotide (FAD), and flavin mononucleotide (FMN) binding domains.
