Phage display recombinant monoclonal antibodies are expressed when DNA sequences encoding an antibody's variable regions are fused with a bacteriophage's genes that encode the coat protein. Thus, the phage's coat expresses an antibody fusion protein on its surface. Benefits: Lot-to-lot consistency due to recombinant productionT cells and B cells are lymphocytes, types of white blood cells, that are able to recognize foreign (non-self) antigens. T cells have T-cell receptors on their cell surface; B cells have cell-surface antibodies. Activated B cells divide and differentiate into plasma cells that secrete large amounts of soluble antibody molecules.
