Immunoglobulin is an antibody that is produced by cell plasma and play important role in immune response of the mucus membrane. It act by recognising particular antigens like bacteria and viruses and bind to the antigens in order to cause their destruction. Immunoglobulin is classified into 5 classes base on the amount of heavy chains they contain which indicates their different level of immune response to invading antigens.
These are 1gG, 1gA, 1gM, 1gE and 1gD. Each contains different number of heavy chain constant to perform different functions of immune response at different site of location.
The immunoglobulin are the antibodies that are found in the serum. There are five classes of these antibodies in the serum. These includes the IgG, IgD, IgA, IgM and IgE. They are classified on the basis of difference in the type of heavy chain. IgG, IgA, IgE, IgD contains μ, α, ε-, and δ- heavy chains respectively.
This variation helps each immunoglobulin class to generate a different kind of immune response during different stages of body defense.
