General description

Monoclonal Anti-Nitric Oxide Synthase, Inducible (iNOS) (mouse IgG1 isotype) is derived from the NOS-IN hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized BALB/c mouse. Nitric oxide synthase (NOS) is classified into three types based on molecular mass, subcellular location, and Ca2+ dependence. Type I NOS (150-160 kDa) is found in neurons. It is also called as NOS-1, neuronal NOS (nNOS), brain NOS (bNOS), cerebral NOS, constitutive NOS or Ca2+-regulated NOS (cNOS). Type II (130 kDa), best characterized in macrophages, also known as macrophage NOS (mNOS) or inducible NOS (iNOS). Type III (135 kDa) is found in endothelial cells. It is called as endothelial NOS (eNOS, or ecNOS). Type II NOS is Ca2+ -independent and is expressed in activated macrophages and some glial cells after stimulation. iNOS is also found in several other cell types including hepatocytes, chondrocytes, endothelial cells and fibroblasts.


Monoclonal Anti-Nitric Oxide Synthase, Inducible (iNOS), antibody reacts specifically with inducible-type nitricoxide synthase (iNOS, also termed macNOS and mNOS). It does not react with NOS derived from brain.


synthetic peptide corresponding to amino acids 1126-1144 of nitric oxide synthase (NOS) from mouse macrophage (iNOS, also termed macNOS) conjugated to KLH. The immunogen sequence is highly conserved in rat iNOS and diverges from the human iNOS.

Biochem/physiol Actions

Nitric oxide synthase (NOS) is an enzyme involved in the synthesis of nitric oxide (NO), a free radical generated under physiological conditions by virtually all mammalian cells. NO is formed from arginine by NOS which oxidizes a guanidino nitrogen of arginine, releasing NO and citrulline. NO is a messenger molecule mediating diverse functions including vasodilatation, neurotransmission, and antimicrobial and anti-tumor activities. Various types of NOS may serve a variety of diverse biological pathways.
