Immunoglobulins, Human

Human Immunoglobulins are a diverse class of human antibodies made up mainly by Immunoglobulin G (IgG), which represents approximately 75% of the immunoglobulins in human plasma. Immunoglobulins A (IgA), D (IgD), E (IgE), and M (IgM) make up the remaining 25%. Each class of antibody gets its designation from the heavy and light peptide chains that make up the antibody structure. Browse our of purified forms of IgA, IgE, IgG, and IgM below.
