Types of Immunoglobulin

IgG is the most abundant immunoglobulin in blood, accounting for 60% of all antibodies circulating in the body. It has a relatively long half-life (about 21 days) and is produced by B cells in response to antigenic stimulation. IgM is the next most abundant antibody, accounting for 20% of all antibodies circulating. It has a short half-life (about 7 days) and is produced primarily by plasma cells. IgD is the least abundant antibody found in blood, accounting for about 5% of total serum Ig. It has a very short half-life (less than 24 hours) and is produced by both B and T lymphocytes.

Immunoglobulins are proteins made up of four polypeptide chains, each composed of several different amino acids. They are classified according to their heavy chain composition.

Classes of Immunoglobulins

Immunoglobulins are divided into five classes based on differences in the structure of their heavy chains. These classes are called IgA, IgD, IgE, IgG, and IgM. Each class contains multiple subclasses.


IgA is the first immunoglobulin discovered and is the only antibody present in mucosal secretions such as saliva, tears, milk, and colostrum. IgA is the primary antibody responsible for preventing infection at mucosal surfaces.


IgD is the second most common antibody in circulation; it accounts for approximately 10% of total serum Ig in adults. IgD is involved in regulating immune responses through its ability to modulate the activity of B cells. IgD can bind to antigens without prior sensitization.


IgE is the third most common antibody in circulation. It plays an important role in allergic reactions. IgE binds to mast cell receptors after they have been sensitized with an antigen, causing them to release histamine and other inflammatory mediators.


IgG is by far the most abundant immunoglubin in blood. It is the major antibody responsible for neutralizing foreign pathogens. IgG is the predominant antibody in the serum of mammals. In humans, IgG is further subdivided into 4 subclasses: IgG1, IgG2, IgG3, and IgG4.


IgM is the fourth most common immunoglobulin in circulation. It is the main antibody responsible for initiating humoral immunity against new antigens. IgM is the first antibody produced when the adaptive immune system encounters an antigen.
