title: Primary immune response of guinea pig spleen cells in vitro.
abstract: Spleen cells of the primed guinea pig, when cultured alone, failed to make a primary immune response against heterologous erythrocytes. When supplemented with lymphocytes obtained from mineral oil induced peritoneal exudate (PEL), a primary immune response against sheep, horse and chicken RBC was obtained. The kinetics, dose response and requirement of PELs for this response are reported.
