    “…Bovine respiratory syncytial virus-infected cultures contained much cell-associated virus which could be liberated by sonication to increase the titer of virus stocks. The use of BRSV-infected cells rather than supernates from BRSV-infected cells increased the rate at which a cytopathic effect developed, although it did not substantially increase the titer of virus which was harvested. …”

    Publicado 2021
    “…Consistent with work by others, vector titers reduced as genome size increased. While genomic infectivity accounted for much of this effect, genome sizes exceeding that of clinical HIV-1 isolates result in low titers due to a combination of both low genomic infectivity and decreased packaging efficiency. …”
