Product details

Sandwich ELISA
The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.

Patented technology
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity

Supplementary information

IgA2 also known as Immunoglobulin A2 is an antibody isotype mainly found in mucosal areas. It has a molecular mass of approximately 160 kDa. IgA2 is primarily expressed in the mucosal membranes lining the gut respiratory tract and urogenital tract playing an important role in the immune defense of these surfaces. It differs from IgA1 in the structure of the hinge region which is shorter and less likely to be cleaved by bacterial proteases providing enhanced protection at these sites.
Biological function summary

IgA2 serves as an essential component of the mucosal immune system. It forms complexes with antigenic substances to neutralize pathogens and prevent their adherence to epithelial cells. The dimeric form of IgA2 combined with the secretory component allows it to be effectively transported across mucosal barriers into secretions where it functions without activating complement pathways therefore reducing inflammation. The secretory IgA2 forms a physical barrier on mucosal surfaces trapping microbes and toxins.

Pathways

IgA2 functions within the mucosal immune response pathways and plays an important interaction role with components of the adaptive immune response. It associates with the polymeric immunoglobulin receptor (pIgR) facilitating its transcytosis across epithelial cells into secretions. IgA2 also operates within the immunological network alongside J chain proteins instrumental in forming its dimeric structure important for appropriate secretion and function in mucosal immunity.

IgA2 is connected to immunological conditions like IgA nephropathy and selective IgA deficiency. IgA nephropathy involves deposits of IgA in the kidneys which can lead to inflammatory kidney damage. In selective IgA deficiency individuals may have increased susceptibility to infections at mucosal surfaces due to decreased IgA levels wherein IgA2's role is significant. The interaction of IgA2 with other immunoglobulins becomes a factor in assessing these diseases especially with proteins that influence the immune response's regulation.

Target data

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).
