What makes the antigen binding site specific?

Best Answer:

Antigen binding sites are specific to individual proteins, meaning that the protein will only recognize and bind to a specific antigen. This specificity is important for two reasons. The first reason is that it allows the immune system to target and destroy harmful invaders. The second reason is that it allows the immune system to bind to and activate specific T-cells to help fight infection.
