WebT-cell antigen receptors are found only on the cell membrane. For this reason, T-cell receptors were difficult to isolate in the laboratory and were not identified until 1983. T-cell receptors consist of two polypeptide chains. The most common type of receptor is called alpha-beta because it is composed of two different chains, one called alpha and the other … WebBasic Antibody Structure. Immunoglobulins (Igs) are produced by B lymphocytes and secreted into plasma. The Ig molecule in monomeric form is a glycoprotein with a molecular weight of approximately 150 kDa that is shaped more or less like a Y. Basic structure of the Ig monomer (Figure 1) consists of two identical halves connected by two disulfide bonds.

WebIgM. Immunoglobulin M (IgM) is the third most common serum immunoglobulin accounting for 5–10 per cent of total levels. It is also a component of secretory immunoglobulins at the mucosal surfaces and in breast milk. Secreted IgM normally exists as a pentamer but it can be also detected as a monomer.
