Suppоse yоu аre perfоrming аn Ouchterlony double diffusion аssay loading Ag1 and Ag3 in 2 wells close to the edge and Ab1 and Ab3 in the middle well. Suppose antigen 3 has an epitope in common with antigen 1. One of the antibodies reacts with the epitope common to both antigens. The other antibody reacts with a different epitope on antigen 1 (that is absent on antigen 3). Two precipitin lines form, with a spur pointing toward antigen 3. What does this result indicate?
