IgA, IgD, IgG, IgE, and IgM are different immunoglobulin isotypes. Immunoglobin A (IgA) is found in mucosal tissue and is the front line defense against infection. IgA binds to pathogens to tag them for destruction from other antibodies. The number of therapeutic antibodies in development pipelines is increasing rapidly.

In this review, we aim to highlight the recent advances in the field. We will illustrate the advantages of different ARM approaches and emphasize the importance of a multivalent presentation of the binding units.
Even in the absence of antigen stimulation, a human can probably make more than 10 12 different antibody molecules—its preimmune antibody repertoire. Moreover, the antigen-binding sites of many antibodies can cross-react with a variety of related but different antigenic determinants, making the antibody defense force even more formidable.What type of molecule is an antibody?
