Source / Purification

Monoclonal antibody is produced by immunizing animals with a prokaryotic recombinant protein corresponding to 129 amino acids of the heavy chain constant region of human immunoglobulin A molecule.

Background

Immunoglobulin A (IgA) is one of the five major human immunoglobulin isotypes and the most abundant immunoglobulin in the mucosal immune system. The structure of IgA consists of two identical heavy chains and two identical light chains, linked by disulfide bonds. Human IgA exists as two subclasses, IgA1 and IgA2, that are structurally different in the flexible hinge region (1). The secreted form of IgA (SIgA) is the predominant mucosal antibody that contains two copies of IgA, a joining-chain (J chain), and a secretory component (SC) (2). IgA antibodies are expressed by B cells and are a part of both the innate and adaptive immune response (3). Since IgA antibodies are secreted by mucosa, they are important when studying autoimmune diseases associated with the gastrointestinal tract (4).
