Glycoproteins called immunoglobulins serve as antibodies by acting as a plasma cell reaction to an immunogen. Antigen binding and effector functions are two often occurring Immunoglobulin activities. The precise antigenic determinants that immunoglobulins bind to shield the host from pathogens. Antibody-antigen binding has little biological impact, while antibody-antigen binding activates the secondary effector function. The receptors on immunoglobulins can bind to lymphocytes, basophils, phagocytic cells, and platelets. Immunoglobulin, also known as antibodies, are proteins produced by the immune system that help protect the body against foreign substances such as bacteria, viruses, and other harmful agents. These proteins play a vital role in the body’s immune response, binding to specific antigens and neutralizing them, making them more easily eliminated by other cells in the immune system.
