Immunofluorescent analysis of nNOS (green) showing staining in the cytoplasm and membrane of U251 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with an nNOS polyclonal antibody (Product # PA1-033) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4°C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

PA1-033 detects nNOS from human, rat and mouse samples.
PA1-033 has been successfully used in Western blot, ICC/IF and immunohistochemisty (paraffin) procedures. By Western blot, this antibody detects an ~160 kDa protein. Detects a few non-specific bands in Western blot analysis of rat and mouse brain lysates. This antibody is not recommended for MCF-7, PC-12, SK-N-C or U87-MG cells in Western blot applications.
The PA1-033 immunogen is a synthetic peptide to residues C N(1411) R L R S E S I A F I E E S K(1425) of human nNOS. The peptide sequence is 100% conserved in rat, mouse, frog, and rabbit nNos proteins. This peptide (Cat. # PEP-190) is available for use in neutralization and control experiments.
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) & 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.
iNOS is found in a variety of cell types including macrophages, hepatocytes, synoviocytes, and smooth muscle cells. Cytokines such as interferon-gamma (IFN), tumor necrosis factor (TNF), interleukin-1 and -2, and lipopolysaccarides (LPS) cause an increase in iNOS mRNA, protein, and activity levels. Protein kinase C-stimulating agents exhibit the same effect on iNOS activity. After cytokine induction, iNOS exhibits a delayed activity response which is then followed by a significant increase in NO production over a long period of time.
