This assay employs the quantitative sandwich enzyme immunoassay technique for the quantitative detection of human IgA. The Human IgA ELISA is for research use only. Not for diagnostic or therapeutic procedures.
Immunoglobulin A (IgA) is an antibody that plays a critical role in mucosal immunity. Its heavy chains are of the type α. IgA has two subclasses (IgA1 and IgA2) and can exist in a dimeric form called secretory IgA (sIgA). In its secretory form, IgA is the main immunoglobulin found in mucous secretions, it is also found in small amounts in blood. The secretory component of sIgA protects the immunoglobulin from being degraded by proteolytic enzymes, thus sIgA can survive in the harsh gastrointestinal tract environment and provide protection against microbes that multiply in body secretions. sIgA can also inhibit inflammatory effects of other immunoglobulins. IgA is a poor activator of the complement system, and opsonises only weakly.
