AffiELISA® Human AP36 Kit: Ultra-Sensitive Apelin 36 ELISA Detection

The AffiELISA® Human AP36 Kit uses competitive inhibition enzyme immunoassay technique. The provided microtiter plate comes pre-coated with Apelin 36 (AP36) protein. To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Apelin 36 (AP36) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. Afterward, the TMB substrate solution is added, initiating an enzyme-substrate reaction. To conclude the reaction, a sulphuric acid solution is introduced, causing a color change that can be measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Apelin 36 (AP36) in the samples can be determined.
