Abstract

SUMMARY

The effect of different doses of viral RNA extracted from avian myeloblastosis virus was tested on RIF-free chick embryo cells. The results showed that the number of cells with positive gs-antigen was probably related to the dose of RNA. The specificity of viral RNA action was shown by a fluorescent antibody method and by the use of ribonuclease.
