When antibodies bind antigens, the clumping of antigens results from the antibody having at least two binding regions.
What's the function of the antibody-antigen complex?
Antibodies serve two primary functions: selective binding to antigens to initiate an immune response and activation of other immune system components to combat infections.
- Immunoglobulins' capacity to combat a wide range of diseases is based on their inherent ability to distinguish between distinct antigens.
- Because of their antigen specificity and affinity, antibodies have shown to be a significant and important tool in research, diagnosis, and treatment.
- Although it appears to be a straightforward move, the connection of an antibody and its antigen to form an antigen-antibody complex is made up of a plethora of non-covalent interactions.
Hence, the correct answer is option A
