From: Purification of infectious human herpesvirus 6A virions and association of host cell proteins
Purified HHV-6A is infectious. Cells were infected with non-purified collection media and purified fractions 11–15 directly or in 1:2 and 1:4 dilutions. The infectivity was measured as the fold increase of viral DNA copies per cell (normalized to actin) at 3 dpi and 7 dpi compared to the initial inocula. The fold increase was calculated by dividing the viral DNA copy number per cell with the viral DNA copy numbers in corresponding inocula.
