only the antibody will diffuse.

|
both antigen and antibody will diffuse.

Detailed explanation-1: -In Ouchterlony double diffusion, both antigen and antibody are allowed to diffuse into the gel. This technique can be used to test the similarity between antigens, for example in a study of evolution.
Detailed explanation-2: -Double Immuno-diffusion In double immunodiffusion, both the antibody and antigen are allowed to diffuse into the gel. After application of the reactants in their respective compartments, the antigen and the antibody diffuse toward each other in the common gel and a precipitate is formed at the place of equivalence.
Detailed explanation-3: -When present in the correct ratio, antibody and antigen will form a precipitin, or lattice that precipitates out of solution. A precipitin ring test can be used to visualize lattice formation in solution. The Ouchterlony assay demonstrates lattice formation in a gel.
