Hybridoma technologies for antibody production

Abstract

Hybridoma technology features effective usage of innate functions of both immune cells and cancers, allowing production of hybridoma cells, which continuously generate monoclonal antibodies specific to antigens of interest. For standard generation of hybridoma cells, B lymphocytes must be somatically fused with myeloma cells using various technologies. However, the methods generally do not necessarily result in selective fusion of target B lymphocytes with myeloma cells. To overcome this problem, we have developed a new hybridoma technology that involves preselection of B lymphocytes with target antigens based on immunoglobulin receptors and selective fusion of B cell-myeloma cell complexes with electrical pulses. The advanced methodology, termed B-cell targeting, multitargeting and stereospecific targeting, may be applicable to simultaneous production of monoclonal antibodies, selective production of stereospecific monoclonal antibodies, and also to efficient generation of human monoclonal antibodies for clinical purposes.
