Recombinant monoclonal human IgA2 antibodies against E. coli β-galactosidase

InvivoGen offers two human monoclonal antibodies (mAbs) targeting E. coli β-galactosidase (β-Gal):

  • Anti-β-Gal-hIgA2
  • Human IgA2 Control, a mono-glycosylated anti-β -Gal-hIgA2 alternative.

These antibodies are provided as isotype controls for InvivoGen’s IgA2 mAb collection (see below).  

Both mAbs feature the constant region of the human IgA2 isotype and the variable region of Mouse IgG2a Control (clone: T9C6) targeting E. coli β-Gal. Therefore, they do not react with human targets.

They were generated by recombinant technology, produced in Chinese hamster ovary (CHO) cells, and purified by affinity chromatography.

The human IgA2 is found predominantly in secretory lymphoid tissues, where it plays a critical role in mucosal immunity. It is highly resistant to enzymatic degradation by bacterial proteases, due to a short hinge region. IgA2 displays no complement-dependent cytotoxicity (CDC) and low antibody-dependent cell-mediated cytotoxicity (ADCC).
