Lepidopteran cells, an alternative for the production of recombinant antibodies?

abstract：:The development and production of recombinant monoclonal antibodies is well established. Although most of these are IgGs, there is also great interest in producing recombinant IgAs since this isotype plays a critical role in providing immunologic protection at mucosal surfaces. The choice of expression system for prod...
