Product Description

MA3-030 detects brain nitric oxide synthase (bNOS), inducible NOS (iNOS) and epithelial NOS (eNOS) in bovine, human, mouse and rat tissues. MA3-030 has been successfully used in Western blot, immunofluorescence, immunoprecipitation, and immunohistochemical experiments. By Western blot, this antibody detects an ~130 kDa band representing iNOS in samples first induced with interferon (IFN) and lipopolysaccarides (LPS), an ~155 kDa band in tissues expressing bNOS and an ~140 kDa band in tissues expressing eNOS. Immunohistochemical staining of NOS with MA3-030 yields a pattern consistent with that seen in the literature and depends on the tissue being studied and the localization of the isoforms present. The MA3-030 antigen is purified bovine bNOS. NOS oxidizes a guanidine nitrogen of arginine releasing nitric oxide in the form of a free radical and citrulline. Nitric oxide thus generated acts as a messenger in diverse functions including vasodilation neurotransmission, anti-tumor and anti-pathogenic activities. NOS is classified under three types: neuronal NOS (nNOS) or brain NOS (bNOS); induciblr NOS (iNOS) or macrophage NOS (mNOS); and endothelial NOS (eNOS). This antibody reacts with iNOS, bNOS and eNOS.
