About This Kit
The Human Immunoglobulin A (IgA) Uncoated ELISA Kit contains pre-matched antibody pairs, plates, and reagents for performing quantitative enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of human IgA. Wash Buffer and Stop Solution are needed to complete the ELISA reaction and are sold separately.
Principle of the method
ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Target information
Human IgA, also known as human immunoglobulin A, is an antibody that is produced by the immune system in response to antigens. It is the most abundant immunoglobulin in mucosal secretions, such as saliva, tears, and breast milk, and plays a key role in defense against pathogens at mucosal surfaces. IgA works by binding to specific antigens and preventing them from entering the body's tissues. It can also activate complement and promote phagocytosis by immune cells. Human IgA can be used in research to study the immune response to pathogens and to develop diagnostic tests and therapeutic interventions for infectious diseases.
