Mouse NOS1/nNOS (Nitric Oxide Synthase 1, Neuronal) ELISA Kit
The Mouse NOS1 (nNOS) Nitric Oxide Synthase 1 Neuronal ELISA Kit is a valuable tool for the accurate measurement of NOS1 levels in mouse samples. This kit is specifically designed for use with serum, plasma, and cell culture supernatants, providing researchers with a reliable and reproducible method for studying the role of NOS1 in various biological processes.Nitric oxide synthase 1 (NOS1) is an important enzyme involved in the synthesis of nitric oxide, a signaling molecule with diverse physiological functions. NOS1 is primarily expressed in neurons and plays a critical role in neurotransmission, vascular regulation, and immune response.
Dysregulation of NOS1 activity has been implicated in various diseases, including neurological disorders, cardiovascular diseases, and inflammation.By accurately measuring NOS1 levels in mouse samples, researchers can gain valuable insights into the role of this enzyme in health and disease. The high sensitivity and specificity of the Mouse NOS1 ELISA Kit ensure precise quantification of NOS1 levels, making it an essential tool for research in the fields of neuroscience, cardiovascular biology, and immunology.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse NOS1/nNOS. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Mouse NOS1/nNOS and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Mouse NOS1/nNOS, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Mouse NOS1/nNOS. The concentration of Mouse NOS1/nNOS in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In the brain and peripheral nervous system, NO displays many properties of a neurotransmitter. Probably has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such SRR. Isoform NNOS Mu may be an effector enzyme for the dystrophin complex. |

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
