A similar lock and key approach can be done for antigen (or proteins) [2].
Roughly speaking, an antibody is a very complex molecule having a Y shape as
symbolized in Figure 7.4. An antibody can recognize a specific antigen approaching
one of the two binding sites located on both ends of the Y. The bond is made of
