Principle of Assay
Chicken Mannan Binding Lectin/MBL ELISA Kit (A7720) employs the sandwich enzyme immunoassay technique for the quantitative measurement of chicken Mannan Binding Lectin/MBL in serum, plasma or other biological fluids. An antibody specific for Mannan Binding Lectin/MBL has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Mannan Binding Lectin/MBL present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-Mannan Binding Lectin/MBL Antibody, which binds the captured Mannan Binding Lectin/MBL present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and an HRP-Avidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of Mannan Binding Lectin/MBL captured in each well. The concentration of Mannan Binding Lectin/MBL can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
