Human IgA ELISA Kit

Product details

Human IgA ELISA Kit ab196263 is a rapid single-wash 90-min ELISA kit to measure Human IgA in saliva, urine, plasma, cell culture supernatant, milk, serum. This SimpleStep ELISA® sensitivity is 0.25 ng/mL.

How the assay works
Human IgA SimpleStep ELISA® 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.

Assay Specificity
This kit recognizes both native and purified Human IgA protein in serum, plasma, milk, urine, saliva, and cell culture media samples only. Cell and tissue extracts have not been tested with this kit.

Human Immunoglobulin A (IgA) belongs to the immunoglobulin family of proteins which include Human IgG, IgE, and IgM, and are known as antibodies. IgA has an essential role in mucosal immunity. IgA is the second most common serum Ig and is about one-fifth of the concentration of IgG, however it is the most abundant immunoglobulin in secretions, such as saliva, mucus, sweat, and tears. In normal human serum, IgA is found mainly as a monomeric, alternatively, in secretions, IgA is found as a dimer containing two additional proteins, secretory piece, and a J chain. The secretory piece is synthesized in the epithelial cells and is added to IgA as it passes into the secretions, protecting it from degradation. IgA works is with lysozymes to hydrolyze carbohydrates in bacterial cells walls to clear the infection. The most common disease associated with high levels of IgA in the kidney is IgA nephropathy, aka Berger's disease. There is no clear clarification as to why IgA deposits occur in the kidney, however abnormality in the immune system is a possibility. Other diseases that IgA is associated with are Celiac disease and Henoch-Schonlein purpura (HSP).
