    IgA Antibody (A2A-13) is a mouse monoclonal IgG1 antibody that detects Immunoglobulin A (IgA) in human samples through applications such as western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). IgA plays a crucial role in the mucosal immune system, serving as the first line of defense against pathogens that enter the body through mucosal surfaces, such as the gastrointestinal and respiratory tracts. IgA is primarily produced by B cells located in gut-associated lymphoid tissues, where daily production surpasses that of all other immunoglobulins, highlighting its importance in maintaining mucosal immunity. The structure of IgA is particularly significant, as IgA typically exists as a dimer, which enhances binding to pathogens and neutralizes them effectively. This dimeric form is stabilized by a joining (J) chain and is transported to mucosal surfaces via the polymeric immunoglobulin receptor (pIgR), ensuring IgA is readily available where most needed. The IgA heavy chain is an α-chain, while the light chains can be either κ- or λ- chains, contributing to the diversity of IgA molecules. With its unique structure and function, IgA is essential for protecting mucosal surfaces from infections, making anti-IgA antibody (A2A-13) a valuable tool for researchers studying immune responses and mucosal health.
