Optimization of stereospecific targeting technique for selective production of monoclonal antibodies against native ephrin type-A receptor 2.

High priority stereospecific targeting (SST) featuring selective production of conformation-specific monoclonal antibodies was directed against a native receptor, EphA2 (ephrin type-A receptor 2). A critical point for this technology is selection of sensitized B lymphocytes by antigen-expressing myeloma cells through their B-cell receptors (BCRs). The essential point is that antigens expressed on myeloma cells retain their original three dimensional structures and only these are recognized.
