Immune system is a defense system that enables us to resist infections. The immune system is composed of two types of immunity- the innate or non-specific immunity and the adaptive or specific immunity. The innate immunity is the first line of defense against invading organisms while the adaptive immunity acts as a second line of defense and also gives protection [...]
Antigen (Ag) antibody (Ab) reactions occur when an antigen combines with a corresponding antibody to produce an immune complex. Therefore, an antigen-antibody reaction is thus a bimolecular association which is similar to an enzyme-substrate interaction but the only difference is that antigen-antibody reaction does not lead to an irreversible chemical interaction. The basis for antigen-antibody reactions are the non-covalent interactions [...]
