Antibodies are therefore key elements in all vertebrate immune systems.
That is the first point. Which provokes the notion that it might somehow be possible to use the high specificity of antibodies in catalysis. And the notion is correct. These resultant antibodies are highly specific for binding to the transition state, and they will be potentially capable of catalyzing the reaction. Antibody catalysis has become a multifaceted field of research involving many bridges between the biological and chemical sciences.
