PATHOLOGY

Detailed explanation-1: -Immunoglobulins (Ig) or antibodies are glycoproteins produced by plasma cells. B cells are instructed by specific immunogens, for example, bacterial proteins, to differentiate into plasma cells.

Detailed explanation-2: -An antibody is a protein produced by the body’s immune system when it detects harmful substances, called antigens.

Detailed explanation-3: -Immunoglobulin G (IgG): This is the most common antibody. It’s in blood and other body fluids, and protects against bacterial and viral infections. IgG can take time to form after an infection or immunization.

Detailed explanation-4: -Immunoglobulins are attached to the B cell membrane while antibodies float in the circulation. The main difference between immunoglobulin and antibody is that immunoglobulin has a transmembrane domain in order to be attached to the plasma membrane whereas antibody does not have a transmembrane domain.
