Human NPS (Neuropeptide S) ELISA Kit

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human NPS. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human NPS. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human NPS in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Modulates arousal and anxiety. May play an important anorexigenic role (By similarity). Binds to its receptor NPSR1 with nanomolar affinity to increase intracellular calcium concentrations (PubMed:15312648, PubMed:16790440) [The Uniprot Consortium]
