* Immunoglobulin G (IgG): This is the most common type of antibody. It is found in blood and other body fluids, and it protects against a wide range of infections.

* Immunoglobulin A (IgA): This type of antibody is found in saliva, tears, and breast milk. It helps to protect against infections of the respiratory and digestive tracts.

* Immunoglobulin M (IgM): This type of antibody is produced early in the immune response, and it helps to clear infections.

* Immunoglobulin D (IgD): This type of antibody is found on the surface of B cells, and it helps to activate the immune system.

* Immunoglobulin E (IgE): This type of antibody is involved in allergic reactions.
