Abstract
Conclusions
The results outlined above including (a) the presence in the purified samples of a uniform and high specific activity, (b) the demonstration that normal macro-molecular constituents are largely eliminated by the purification procedures, and (c) the fact that the samples are relatively mono-disperse in the transparent ultracentrifuge provide strong evidence that the preparations consist of essentially pure Lansing virus.
Presented at the Symposium of the Division of Biological Chemistry of the American Chemical Society on Biochemical and Biophysical Studies on Viruses at Atlantic City on April 12, 1946.
