Effect of propane sultone pretreatment on Friend virus leukemogenesis in mice

Propane sultone (PS) injected i.p. 24 or more hours before Friend leukemia virus increased the incidence of lymphoma in SJL/J mice and at a higher dose increased the incidence of erythroleukemia in B10SJF1 mice. PS at the same time also decreased hematopoietic stem cell clonogenicity.
