Haemolytic Plaque Formation by Unimmunized Mouse Peritoneal Lymphocytes

BUSSARD1 has recently reported that when peritoneal cells from unimmunized mice are incubated at 37° C with sheep red blood cells and complement in a film of carboxymethyl-cellulose gum (CMC)2, they produce plaques of haemolysis. He also presented some evidence that this lysis results from the production of antibody.
