Human OXA (Orexin A) ELISA Kit

Description

Synonym: Hypocretin-1. This Human OXA (Orexin A) ELISA Kit applies to the in vitro quantitative determination of Human OXA concentrations in serum, plasma and other biological fluids. Type:Competitive, Assay time:1.5h, Detection type:Colormetric, Precision:CV<10%, Assay Range:12.35-1000pg/mL, Sensitivity:5.12pg/mL, Recovery:80%-120%, Cross reactivity:The kit detected Human OXA in the samples and no significant cross-species reactions were found. Detection Principle:This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human OXA. During the reaction, Human OXA in the sample or standard competes with a fixed amount of Human OXA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Human 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 Human OXA in tested samples can be calculated by comparing the OD of the samples to the standard curve.
