tcue2541 ELISA Kit for Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF)

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF), 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. The concentration of Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
