Stages of Antigen-Antibody Reaction
The interaction between an antigen and an antibody occurs in three stages:
- Primary Stage: The first stage involves the formation of the Ag-Ab complex. It is rapid and and reversible without any visible effects.
- Secondary Stage: It leads to observable phenomena such as agglutination or precipitation It is slow and irreversible with visible effects.
- Tertiary Stage: It involves the neutralization or destruction of the antigen.
Types of Antigen-Antibody Reaction
The types of antigen-antibody reaction interactions are specific biochemical interactions between antibodies produced by B cells (a subset of white blood cells) and antigens when they approach a distance of several nanometers. This reaction results in agglutination, a process that binds paratopes of antibodies to particular antigens on their topes and sets off a series of immune responses to act against the respective antigens for their elimination or destruction. In this article, we will look into the types of Antigen-Antibody Reaction and the stages, and properties of antigen-antibody reactions.
