The Human OXA (Orexin-A) ELISA Kit is specifically designed for the precise measurement of orexin-A levels in human samples such as serum, plasma, and cell culture supernatants. This kit is characterized by its high sensitivity and specificity, ensuring accurate and consistent results, making it an excellent tool for various research applications.Orexin-A, also known as hypocretin-1, is a neuropeptide that plays a crucial role in regulating wakefulness, appetite, and energy metabolism.
Dysregulation of orexin-A has been implicated in conditions such as narcolepsy, obesity, and sleep disorders, making it a valuable biomarker for studying these disorders and developing potential interventions.By utilizing the Human OXA ELISA Kit, researchers can gain valuable insights into the role of orexin-A in health and disease, facilitating the advancement of scientific knowledge and the development of novel therapeutic strategies.

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with OXA. During the reaction, OXA in the sample or standard competes with a fixed amount of OXA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to OXA. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of OXA in tested samples can be calculated by comparing the OD of the samples to the standard curve.
