Principle of the Procedure

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Goat SOD1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Goat SOD1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substGoate solution is added to each well. Only those wells that contain Goat SOD1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substGoate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentGoation of Goat SOD1. You can calculate the concentGoation of Goat SOD1 in the samples by comparing the OD of the samples to the standard curve.
