Partial Identification of Lysins and Agglutinins in Lymphomatous Mouse Tissue

LYSINS and agglutinins have been extracted from normal mouse tissue, from mammary carcinomas of female C 3 H mice, and recently from human leukæmic cells 1 , and from the lymphomatous glands of AKR mice 2 . The lytic materials have been tentatively termed ‘soap-like’ and ‘lysolecithin-like’, supposedly bound to proteins 3,4 , but in reality the nature of both the lysins and the proteins is still unknown. This communication is concerned with the last point.
