Product details

Mouse IgA SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IgA protein in Serum, Cit Plasma, EDTA Plasma, Hep Plasma. Quantitate Mouse IgA with 2.2 pg/ml sensitivity. SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

Single-wash protocol reduces assay time to 90 minutes or less
        -High sensitivity, specificity and reproducibility from superior antibodies
        -Fully validated in biological samples
        -96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Supplementary information

Immunoglobulin A (IgA) also known as sIgA in its secretory form is an important component of the immune system. With a molecular weight of approximately 160 kDa IgA exists as a monomeric or dimeric structure. It is primarily expressed in mucosal areas such as the respiratory tract gastrointestinal tract and urogenital tract while also being present in secretions like saliva tears and breast milk. In its dimeric form IgA associates with a joining (J) chain and a secretory component which facilitates its transport across mucosal barriers.
Biological function summary

IgA functions as a first line of defense in immune responses occurring at mucosal surfaces. Its primary role is to neutralize pathogens toxins and prevent their attachment and penetration through epithelial cells. This antibody does not form part of a larger complex but plays an important role in immune exclusion by trapping antigens in the mucus layer. Additionally IgA can mediate antibody-dependent cellular cytotoxicity and engage with specific receptors like FcαRI (CD89) on immune cells further enhancing its protective capabilities.

Pathways

IgA participates in the mucosal immune response which is a sub-component of the broader immune system pathways. It is closely associated with the polymeric immunoglobulin receptor (pIgR) which transports IgA to the mucosal surfaces. The pathway involves recombination activation proteins (RAG) during its class-switching process in B cells differentiating from IgM-producing cells to those secreting IgA. These pathways are integral to maintaining the mucosal environment and protecting against pathogens.

Alterations or deficiencies in IgA can lead to increased susceptibility to infections and disorders like IgA nephropathy and celiac disease. In IgA nephropathy IgA deposits in the kidneys result in inflammation and damage to renal tissues. Celiac disease involves an immune reaction to gluten where IgA antibodies against tissue transglutaminase (tTG) contribute to intestinal damage. Both conditions illustrate the importance of IgA in maintaining immune balance and its connection with disease pathologies.

Target data

Ig alpha is the major immunoglobulin class in body secretions. It may serve both to defend against local infection and to prevent access of foreign antigens to the general immunologic system.
