What are Immunoglobulins?

Immunoglobulins - sometimes just referred to as ‘antibodies’ are Y-shaped proteins produced by the white blood cells, that are used by the immune system to neutralize bacteria and viruses. As part of an immune response, immunoglobulins recognize and bind to particular antigens to destroy the target cell.

There are five primary classes of immunoglobulins - IgG, IgM, IgA, IgD and IgE, all of which are distinguished by the type of chains found in the molecule. The differences in chain polypeptides are what are responsible for different immune responses from each of the five classes listed above.
