Fluids from a pooled selection of healthy donors were evaluated for the presence of Human IgA in serum, milk, saliva, and urine using this assay. Results were interpolated from the standard curve in Sample Diluent NS and corrected for sample dilution. The mean levels of Human IgA in serum were 2.45 mg/mL, in milk at 0.74 mg/mL, in saliva at 0.94 mg/mL and in urine at 0.05 mg/mL.

Serum of ten individual healthy human male donors was measured in duplicate. Interpolated dilution factor corrected values (to neat sample) are plotted (mean +/- SD, n=2). The mean IgA concentration was determined to be 3.978 mg/mL with a range of 1.016 – 9.476 mg/mL.

제품 세부 정보

Human IgA ELISA Kit, Chemiluminescent (ab325622) is a rapid single-wash sandwich 55 min ELISA to measure Human IgA in Serum, Citrate Plasma, EDTA Plasma, Heparin Plasma, Urine, Saliva, Milk, Cell Culture Supernatant with a sensitivity of 0.09 ng/mL.

How the assay works

Human IgA ELISA Kit, Chemiluminescent (ab325622) SimpleStep Ignite™ 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 during a 30 min only incubation, significantly reducing assay time. By utilizing a chemiluminscent detection method this improves the sensitivity and dynamic range when compared to traditional colormetric ELISAs.

Assay Specificity

Our SimpleStep Ignite™ ELISA kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

타겟 정보

Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed : 20176268, PubMed : 22158414). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for a particular antigen (PubMed : 17576170, PubMed : 20176268). Ig alpha is the major immunoglobulin class in body secretions (PubMed : 2241915).
