Rat SPX (Spexin) ELISA (Small Sample Volume)

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat SPX. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat SPX. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat SPX, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Rat SPX in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Plays a role as a central modulator of cardiovascular and renal function and nociception. Also plays a role in energy metabolism and storage. Inhibits adrenocortical cell proliferation with minor stimulation on corticosteroid release (PubMed:20045034, PubMed:22038051) , Acts as a ligand for galanin receptors GALR2 and GALR3 (By similarity). Intracerebroventricular administration of the peptide induces an increase in arterial blood pressure, a decrease in both heart rate and renal excretion and delayed natriuresis. Intraventricular administration of the peptide induces antinociceptive activity. Intraperitoneal administration of the peptide induces a reduction in food consumption and body weight. Inhibits long chain fatty acid uptake into adipocytes. Also induces contraction of muscarinic-like stomach smooth muscles (PubMed:24550067) , Intracerebroventricular administration of the peptide induces a decrease in heart rate, but no change in arterial pressure, and an increase in urine flow rate. Intraventricular administration of the peptide induces antinociceptive activity (PubMed:22038051) [The Uniprot Consortium]
