Enzyme-linked secondary antibodies are applied as detection antibodies that also bind specifically to the antibody's Fc region (nonspecific). The plate is washed to remove the unbound antibody-enzyme conjugates. A chemical is added to be converted by the enzyme into a color or fluorescent or electrochemical signal.
If the enzyme-linked antibody binds to human antibodies, the enzyme will create a detectable change that indicates the presence and amount of the antibody in the patient sample. (Â© 1994-2006).
