General description

Monoclonal Anti-Nitric Oxide Synthase-Brain (bNOS) (mouse IgG1 isotype) is derived from the NOS-B1 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from immunized BALB/c mice. Nitric oxide synthase (NOS) has been localized in many different cell types. Type I NOS is found in neurons. It is a 150-160 kDa protein, also called NOS-1, neuronal NOS (nNOS), brain NOS (bNOS), cerebral NOS, constitutive NOS or Ca2+- regulated NOS (cNOS). bNOS is present also in skeletal muscle, where it is complexed with dystrophin, and is absent in Duchenne′s muscular dystrophy, which perhaps accounts for symptoms of the disease.


Monoclonal Anti-Nitric Oxide Synthase, Brain (1-181) antibody is specific for nitric oxide synthase (NOS) derived from brain (bNOS, 150-160 kDa and several breakdown products of lower M.W.). The product does not bind to NOS derived from macrophages (mNOS) and endothelial cells (eNOS). This antibody is specific for bNOS in humans, goats, pigs and rats.


recombinant neuronal NOS fragment (amino acids 1-181) from rat brain.

Biochem/physiol Actions

Nitric oxide synthase is an enzyme that catalyzes the formation of nitric oxide. Nitric oxide is responsible for regulating several biochemical functions such as hemostasis, neurotransmission and vascular injury response . Mutations in nitric oxide synthase gene have been associated with diabetic nephropathy.
