Immunoglobulins are antibodies. The five main classes in humans are IgA (found in mucosal areas like the gut), IgD (function not fully - understood but present on B - cell surfaces), IgE (involved in allergic reactions), IgG (most abundant in blood and can cross the placenta), and IgM (first antibody produced in response to an antigen).

IgA, IgD, IgE, IgG, IgM
