Large amounts of enveloped virus have been produced at high titer using a hollow fibre bioreactor

Although lytic viruses have been produced in a hollow fibre bioreactor [1] this continuous mode of cell culture is much better adapted to production of enveloped viruses that bud off from the cell surface. Daily collections of small volumes of cell supernatant can be taken. In this way, HCV virus has been produced with Huh7.5 cells over weeks at remarkably high titer using a leading to large total amounts [2].

In vitro anti-viral PK/PD

The hollow fibre culture system has been used to model human PK for anti-virals and to take samples for analysis over long periods of operation [more…]
