Matched Antibody Pair

The Porcine Interleukin 4 Antibody Pair Kit comes with pre-matched antibody pairs, standards, and streptavidin-HRP to develop your own enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of pig IL-4. Buffer reagents needed to complete the ELISA reaction are sold separate as a Buffer Kit for Antibody Pairs (Catalog No. CNB0011). The Assay Buffer included in this Buffer Kit can be used as a blocking reagent for ELISA plates as well as a diluent for ELISA standards and samples, detection antibody, and HRP conjugate. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, binding to the target on a different epitope from the capture antibody. A conjugated enzyme has been incorporated into the assay. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
