Test Principle: This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Universal NA/NE. During the reaction, Universal NA/NE in the sample or standard competes with a fixed amount of Universal NA/NE on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Universal NA/NE. 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 Universal NA/NE in tested samples can be calculated by comparing the OD of the samples to the standard curve.
Cross reactivity: This kit recognizes Universal NA/NE in samples.No significant cross-reactivity or interference between Universal NA/NE and analogues was observed
