AffiELISA® Pan LXA4 Kit: Max Sensitivity Lipoxin A4 ELISA Detection

The AffiELISA® Pan LXA4 Kit uses competitive inhibition enzyme immunoassay technique. The provided microtiter plate comes pre-coated with Lipoxin A4 (LXA4) protein. To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Lipoxin A4 (LXA4) 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 Lipoxin A4 (LXA4) in the samples can be determined.
