General description

Binding Capacity: One mL of antibody binds 3-4 mg human IgA. Elution Capacity is 2-4 mg/mL.
IgA antibody plays an essential role in mucosal immunity. It has shown to bind immunogens/pathogens to restrict them from entering the mucosal membrane. The Anti-Human IgA (α-chain specific) product increases sensitivity to human IgA without cross-reactivity to other substances. Offering minimal interspecies cross reactivity to mouse or a rat, making it ideal for use in screening antibodies produced by a hybridoma cells containing a mouse or a rat immunoglobulins.

Immunogen

IgA produced from transformed cell line of human Epstein-Barr virus.

Application

Affinity chromatography using anti-human IgA antibody linked to agarose was performed to purify proteins from 2E9IgA1 transfectant cells.
Anti-Human IgA (α-chain specific)-Agarose antibody produced in goat has been used in affinity chromatography and quantitative enzyme linked immunosorbent assay (ELISA).

Physical form

Suspension in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

We have previously generated human monoclonal anti-human immunodeficiency virus type 1 (anti-HIV-1) antibodies 2F5IgG and 2G12IgG with an exceptional cross-clade neutralizing potential. 2F5IgG and 2G12IgG passively administrated to macaques were able to confer complete protection from both intravenous and mucosal

Multiple myeloma (MM) is a B-cell malignancy. The monoclonal immunoglobulin, secreted by myeloma plasma cells, carries unique antigenic determinants (idiotype [Id]) that can be regarded as a tumor-specific antigen. Id-based immunotherapy has been explored in myeloma patients for the purpose

The hallmark of a mucosal immune response is the production of antigen-specific secretory IgA (S-IgA) antibodies in external secretions. S-IgA consists of ten polypeptides produced in two different cell lineages. The heavy and light chains in plasma cells assemble into
