AffiELISA® Mouse NPTX1 Kit: Super-Sensitive Neuronal Pentraxin I ELISA Detection

The AffiELISA® Mouse NPTX1 Kit uses Sandwich enzyme immunoassay. The provided microtiter plate comes pre-coated with an antibody specific to Neuronal Pentraxin I (NPTX1) . To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Neuronal Pentraxin I (NPTX1) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. After TMB substrate solution is added, only those wells that contain Neuronal Pentraxin I (NPTX1) , biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Neuronal Pentraxin I (NPTX1) in the samples can be determined.
