RayBio® Sandwich-based ELISAs employ specific capture antibodies coated on a 96-well plate. Standards and samples are pipetted into the wells; the target protein in the standards and samples binds to the immobilized antibody. The wells are washed and the biotin-labeled detection antibody is then added. After washing away the unbound biotinylated antibodies, HRP-conjugated streptavidin is pipetted to the wells, followed by a colorimetric substrate solution. The intensity of color development in the wells is proportional to the amount of target protein bound.
