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 Sialic Acid Acetylesterase (SIAE). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Sialic Acid Acetylesterase (SIAE). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, o
