Specificity
This monoclonal antibody is specific to heavy chain of IgA and shows minimal cross-reaction with heavy chains of other immunoglobulins. It is reactive with both IgA1 and IgA2 subclasses of Alpha heavy chain. It reacts with the third constant domain (CH3) of the alpha chain of IgA molecules. Immunoglobulins are four-chain, Y-shaped, monomeric structures comprised of two identical heavy chains and two identical light chains held together through inter-chain disulfide bonds. The chains form two domains, the Fab (antigen binding) fragment and the Fc (constant) fragment. Immunoglobulin A (IgA) is the main protein of the mucosal immune system. It is generated by B-cells in gut-associated lymphoid tissues. Daily production of IgA exceeds that of any of the other immunoglobulins.IgA exists mainly in dimers but can also exist as polymers or as monomers. Dimers and polymers contain a joining (J) chain that can be bound by the polymeric immunoglobulin receptor (pIgR) for transportation of the molecule to mucosal surfaces. The most common feature of plasmacytomas, and certain non-Hodgkins lymphomas is the restricted expression of a single heavy chain class. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is clonal and therefore malignant.

Applications/Dilutions

Dilutions
  • Flow Cytometry 1-2 ug/million cells
  • Immunocytochemistry/Immunofluorescence 1-2 ug/ml
  • Immunofluorescence 0.5 - 1.0 ug/ml
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin 1-2 ug/ml
Application Notes
Immunofluorescence: 1-2ug/ml 30 min RT.
Immunohistochemistry (Formalin-fixed): 1-2ug/ml 30 min RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.

Alternate Names for IgA Antibody (HISA43)

  • IgA
  • Immunoglobulin A

Background

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. The most common feature of plasmacytomas, and certain non Hodgkin's lymphomas is the restricted expression of a single heavy chain class. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is clonal and therefore malignant. This antibody is useful in the identification of leukemias, plasmacytomas, and certain non Hodgkin's lymphomas.
