Size of infectious DNA from human and murine cytomegaloviruses.

摘要: Viral DNA was isolated from human and murine cytomegalovirus by equilibrium centrifugation in cesium chloride gradients. The size of the measured relative to T4 velocity sedimentation neutral glycerol gradients, fractions were assayed for infectious DNA. Infectious sedimented as a single peak with an estimated molecular weight 136 X 10(6). detected two peaks weights 130 10(6) 150
