Studies on the Aggregation Reactions and Basic Dye Binding of Tobacco Mosaic Virus
1. Aqueous solutions of tobacco mosaic virus were found to undergo a number of spontaneous changes on standing in the cold. The results of pH measurements, acid and base titrations, intrinsic viscosity determinations, studies on the irreversible binding of methylene blue with the virus, ultraviolet absorption, and the extent of nucleic acid splitting by heat denaturation indicated the occurrenc...
متن کاملSolubility Studies on Purified Tobacco Mosaic Virus
Different samples of purified tobacco mosaic virus show a relatively wide variation in solubility in ammonium sulfate solution. This variation and the type of solubility curve obtained in the presence of varying amounts of solid phase show that the purified virus whether isolated by mild treatment with ammonium sulfate or by ultracentrifugation is not a homogeneous chemical substance but contai...
متن کاملImmunologic Reactions with Tobacco Mosaic Virus
1. Antisera were produced, separately, in rabbits to normal sap from healthy Turkish tobacco plants and to irus-sap from tobacco plants, affected with mosaic disease. 2. The immunologic reactions of the antisera were studied by means of: (a) Alexin-fixation tests. (b) Precipitation experiments, including: Precipitin-absorption tests with the same tobacco virus multiplied in tobacco, tomato, pep...
متن کاملChemical Studies on the Virus of Tobacco Mosaic
A method for the isolation, from mosaic-diseased Turkish tobacco plants, of a crystalline protein possessing the properties of tobacco mosaic virus has been described (1, 2). The method consists essentially in precipitation of the globulin fraction from a dilute disodium phosphate extract of frozen, macerated, infected plants with ammonium sulfate, and the removal of most of the remaining color...
متن کاملStudies on the Sonic Treatment of Tobacco Mosaic Virus
Centrifugally purified samples of tobacco mosaic virus were subjected to intense sound vibrations of 9,000 cycles per second for 0, 2, 8, 16, 32, and 64 minutes. The viscosity and stream birefringence of the samples decreased with time of sonic treatment, but no chemical changes were found. Electron micrographs of the samples show that the particles are broken perpendicular to their long axis. ...
