Immunoglobulins are basically proteins that function as antibodies. The terms antibody and immunoglobulin are often used interchangeably. Immunoglobulins are found in blood and other tissues and fluids. They are made by the plasma cells that are derived from the B cells of the immune system.B cells of the immune system become plasma cells when activated by the binding of a specific antigen on its antibody surfaces.hey are made by the plasma cells that are derived from the B cells of the immune system.

IgA. Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in mucosal immunity. More IgA is produced in mucosal linings than all other types of antibody combined; between three and five grams are secreted into the intestinal lumen each day.This accumulates up to 15% of the total immunoglobulin produced in the entire body.his chain is formed in the IgA-secreting cells. The oligomeric forms of IgA in the external (mucosal) secretions also contain a polypeptide of a much larger molecular mass (70 kD) called the secretory component that is produced by epithelial cells.
