The DeQuanto Infliximab (Remicade) PK ELISA kit is an ELISA based immunoassay. The Infliximab present in the sample binds to pre coated TNF on polystyrene microtiter plate. Non bound or the excess substances are removed by washing. Horseradish peroxidase (HRP) labeled anti-human IgG Fc specific antibody is added to the wells which binds to the TNF/Infliximab complex in the wells. Following a wash to remove any unbound antibody-enzyme reagent, substrate solution is added to the wells. A color product is formed in proportion to the amount of Infliximab present in the sample or standards. The color development is stopped by addition of a stop solution. The absorbance is measured at 450 nm in a microtiter plate reader. The concentration of Infliximab in a sample can be interpolated from the standard curve.
