A microculture method for the generation of primary immune responses in vitro.
A microculture method for the generation and study of the primary immune response of murine spleen cells to defined antigens in vitro is described. Many of the variable parameters which occur in culture systems have been studied in an attempt to define the optimal culture conditions for this system. Cultures of 10(6) CBA spleen cells consistently produced an immune response of 300-600 hapten-specific plaque-forming cells after 3 days of incubation with the T cell-independent antigens DNP-POL and NIP-POL. Cultures were set up in Microtest II tissue culture plates in a volume of 0.2 ml of medium containing 10(-4) M 2-mercaptoethanol. The system described has the advantages of being highly efficient and reproducible and utilises small amounts of cells, medium and antigen. It provides a simple, economic and reliable approach for the systematic study of the immune response in vitro.
