| Table 1. The Five Immunoglobulin (Ig) Classes | |
|---|---|
| Name | Properties |
| IgA | Found in mucous, saliva, tears, and breast milk. Protects against pathogens. |
| IgD | Part of the B cell receptor. Activates basophils and mast cells. |
| IgE | Protects against parasitic worms. Responsible for allergic reactions. |
Where are the 5 classes of antibodies found?
There are five immunoglobulin classes (isotypes) of antibody molecules found in serum: IgG, IgM, IgA, IgE, and IgD. They are distinguished by the type of heavy chain they contain.
What are the five different isotypes of antibodies and the properties of each isotype?
In mammals, antibodies are classified into five main classes or isotypes – IgA, IgD, IgE, IgG and IgM. These differ in the sequence and number of constant domains, hinge structure and the valency of the antibody. …
Which of the five types of antibodies are involved in allergic reactions?
For example, antibodies made in response to a tuberculosis infection attach only to tuberculosis bacteria. Antibodies also work in allergic reactions. Occasionally, antibodies may be made against your own tissues….The five major types of antibodies are:
- IgA.
- IgG.
- IgM.
- IgE.
- IgD.
What are 5 examples of antigens?

What do antibodies do for your body?
Antibodies are the proteins which are present in the immune system of the humans. They help the immune system in identifying any foreign objects whether bacteria, viruses or other pathogens in the body.
What are the functions of antibodies?
Major functions of the antibodies are: Neutralization of infectivity, Phagocytosis , Antibody-dependent cellular cytotoxicity ( ADCC ), Complement-mediated lysis of pathogens or of infected cells: Antibodies activate the complement system to destroy bacterial cells by lysis. Transcytosis, mucosal immunity & neonatal immunity.
