Guide to the structural components that make up an antibody - heavy chains, light chains, F(ab)/Fc regions - and antibody isotypes. Download our comprehensive guide to antibody basics. Updated May 9, 2022.
The five main classes of antibodies (immunoglobulins): IgG, IgA, IgD, IgE, and IgM. (more) Antibodies are grouped into five classes according to their constant region. Each class is designated by a letter attached to an abbreviation of the word immunoglobulin: IgG, IgM, IgA, IgD, and IgE.
Jan 17, 2023 · An antibody (formally called immunoglobulin) is a large Y-shaped glycoprotein produced by B-cells and used by the immune system to identify and neutralize pathogens. Antibodies are produced by B cells, and are either secreted into circulation or remain expressed on the surface of the B cell.
Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.
Oct 31, 2023 · Antibodies contain four polypeptides: two identical (to each other) heavy chains in a “Y” formation and two idenitical (to each other) light chains on the outside of the top of the “Y” portion. Each antibody has a unique variable region, which is responsible for antigen detection and specificity.

May 1, 2023 · The five antibody classes produced by the body include IgG, IgM, IgA, IgD, and IgE. IgM is the first antibody produced and acts as a B-cell surface immunoglobulin (Ig). Complex signaling pathways then induce isotype switching to produce immunoglobulins more fit for fending off the particular pathogens. [1] [2]
