PRIMARY ANTIBODY RESPONSE IN VITRO IN PERITONEAL CELLS

Abstract
Peritoneal cells (PC), from nonimmunized mice, incubated in a carboxymethyl cellulose gum containing sheep red blood cells (SRBC) and guinea pig complement (following the technique of Ingraham and Bussard) start to produce plaques of hemolysis 20 hr after the beginning of incubation at 37°C.
