Abstract
The infectious quality of the erythromyeloblastic leukosis virus is most stable at pH about 7, and the region favorable for relative stability extends from pH about 6-9. Enzymatic activity of the same preparations to dephosphorylate adenosine triphosphate was more stable than infectious capacity, but the pH regions of optimum stability were essentially identical. There was no evidence in electron micrographs of effect on the physical characters of the particulate material of the plasma nor were there any differences in the numbers of the particles related to pH concentration.Keywords
