| Popis: | A decrease in the sedimentation rates of the measles virus nucleocapsid, and the RNA contained within, were observed during acute measles virus infection when the growth conditions of Vero cells were altered. The change in sedimentation rates of virus nucleocapsids in these experiments was apparently due to the physiological state of the cell and was independent of the history of the measles virus used for infection since: (i) the same virus stock was used to infect cells from which nucleocapsids were prepared, (ii) nucleocapsid sedimentation rates were rapid when Vero cells freshly revived from liquid nitrogen were infected, but nucleocapsid profiles showed no decrease in the amount of slowly sedimenting material using the same cells and changing the virus preparation used for infection. Frequent cell splittings and numerous medium changes were among the growth factors which appeared to correlate to slowly sedimenting particle production. Changes in the amount of self-complementarity of the measles virus RNA were also observed under these conditions. |
