It causes pathogens to stick together.
The process by which an antibody binds to an antigen is called antigen-antibody binding. This occurs when the antibody recognizes and attaches to a specific part of the antigen, forming a complex that helps the immune system identify and neutralize the antigen.
When an antigen and its matching antibody meet in the body, the antibody binds to the antigen, marking it for destruction by the immune system. This process helps to neutralize the antigen and prevent further harm to the body.
Epitope, it is the part of the antigen that is recognized and binds by the antibodies.
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.

It is the place where antibody binds after recognizing the antigen
An antigen is actually foreign or toxic to the human body. It stimulates an adaptive immune response and binds to a antibody.
To enhance the function of phagocytosis. The antibody binds to the antigen (on the organism). The antibody also binds to the phagocyte thus facilitating the coming together of the antibody and phagocyte and phagocytosis can then proceed.
Sandwich ELISA directly detects the antigen using two antibodies, while indirect ELISA detects the antigen using a primary antibody and a secondary antibody that binds to the primary antibody.

epitopes on the antigen while the paratopes on the antibody
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
