NOS1 Antibody (A-11) is a mouse monoclonal IgG1 kappa light chain antibody engineered to detect neuronal nitric oxide synthase (nNOS), also known as NOS1 or ncNOS. NOS1 monoclonal antibody (A-11) targets an epitope comprising amino acids 2-300 of the human NOS1 protein, ensuring reliable recognition of NOS1 across mouse, rat, and human species in applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Neuronal nitric oxide synthase is pivotal in the production of nitric oxide (NO), a critical signaling molecule involved in diverse biological processes including neurotransmission, vascular regulation, and immune response modulation. The function of NOS1 is essential for maintaining cellular communication and homeostasis, as NOS1 catalyzes the conversion of L-arginine to NO, a reaction that requires homodimerization and the presence of multiple cofactors such as NADPH, FAD, FMN, calmodulin, tetrahydrobiopterin, and heme. Understanding the activity of NOS1 is important because NOS1 differentiates the roles of various nitric oxide synthase isoforms, including the inducible NOS2 and the endothelial NOS3, each contributing uniquely to physiological and pathological states. NOS1 mouse monoclonal antibody (A-11) is available in both non-conjugated form and a range of conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates, making NOS1 monoclonal antibody (A-11) versatile for numerous experimental setups. By facilitating the precise detection and study of NOS1, NOS1 (A-11) antibody supports advanced research into NO-mediated signaling pathways and their implications in health and disease, ultimately contributing to the development of targeted therapeutic strategies.

I used this antibody to stain nNOS of mouse origin and it worked quite well. But can this antibody recognize both splicing variants, nNOSalpha and nNOSbeta of mouse origin?

Asked by: llin
Thank you for your question. The exact epitope recognized by this mouse monoclonal antibody, NOS1 (A-11): sc-5302, has not been determined. The antibody is raised against amino acids 2-300 of NOS1 of human origin. According to Uniprot, mouse isoform nNos beta is missing amino acids 1-230 (http://www.uniprot.org/uniprot/Q9Z0J4#sequences). Therefore, it is possible that this antibody could recognize both variants.

Rated 1 out of 5 by from NOS1 in pig gutAt necropsy, intestinal tract of pig were dissected. Sample was washed in NaCl 0.9% and post-fixed by immersion for 7 h in 10% buffered formalin (pH 7.4), dehydrated through a graded series of ethanol and finally embedded in Paraplast X-TRA. Four-µm thick sections were cut in the transversal plane and collected on silane-coated slides. After deparaffinization and rehydratation, the Avidin/Biotin blocking was performed and slides were then incubated overnight at room temperature in a dark moist chamber with anti-NOS1 (A-11) (sc-5302) diluted 1:100 in phosphate buffer saline (PBS). After washing in PBS, sections were incubated for 1.5 hour with Goat Anti-Mouse IgG Antibody (H+L), Biotinylated (6 μg/ml, Vector Laboratories Inc., Burlingame, CA, USA) in a dark moist chamber. The sections were washed twice in PBS and treated with Fluorescein–Avidin D (Vector Laboratories Inc., Burlingame, CA, USA). Finally, the slide with tissue sections was embedded in Vectashield Mounting Medium with DAPI (H-1200, Vector Laboratories Inc., Burlingame, CA, USA) and observed using a Confocal Laser Scanning Microscope (FluoView FV300, Olympus, Tokyo, Japan). Our results did not demonstrate any NOS1-immunopositivity in any region of the pig gut.
