Answer :
The binding of an antibody to an antigen can result in all of the following except release of perforin.
Antigen Binding:
When antibodies and particular antigens are brought within a few nanometres of each other, a biochemical reaction known as an antigen-antibody (Ag-Ab) interaction occurs. A series of immunological reactions to act against the relevant antigens for their removal or destruction are started when paratopes of antibodies bind to specific antigens on their epitopes.
Immunogens are any foreign chemicals that, once entering our bodies, occasionally cause a cascade of immunological reactions. While others, known as haptens, require the assistance of other molecules (carrier proteins) in order to activate an immunological response. All of the immunogens and haptens are referred to as antigens.
Simply said, an antibody is a substance that the immune system makes in reaction to antigens. In essence, antigens are what cause the production of antibodies. To elicit an immunological response, they interact with one another.
