The Free Beta hCG ELISA kit relies on the sandwich ELISA principle to detect free beta-hCG in a sample. Microtiter wells are coated with an antibody that specifically binds to free beta-hCG. The test sample, containing the free beta-hCG, is added to the wells, where it binds to the antibody. A second antibody, enzyme-conjugated, is then added, which also binds to free beta-hCG, creating a "sandwich". After unbound components are washed away, a substrate is added, which reacts with the enzyme, producing a detectable color change. The intensity of this color is directly proportional to the concentration of free beta-hCG in the sample
