测试原理 | This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Human Salusin α. During the reaction, Human Salusin α in the sample or standard competes with a fixed amount of Human Salusin α on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Human Salusin α. 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 Salusin α in tested samples can be calculated by comparing the OD of the samples to the standard curve. |
由于实验操作条件的不同(如操作者、移液技术、洗板技术和稳定条件等),标准曲线的OD值会有所差异。以下数据和曲线仅供参考,实验者需根据自己的实验建立标准曲线。
