Subfractionation of rat liver microsomes by the use of rate-zonal centrifugation has been carried out using both normal and induced rats. Phenobarbital and methyl cholanthrene were found to have very distinctive effects on the distribution of cytochr

SummaryPseudomonas phaseolicola bacteriophage ⊘6 containing DS-RNA is capable of inducing interferon with a lower potency than with mycophage obtained from Penicillium stoloniferum. The smaller response with ⊘6 appears to be due to the lipid enve
