Wild-type Marburg virus (MARV) can only be handled in biosafety level 4 facilities. By removing an essential gene from the virus genome, deficient virus particles can be generated that are only capable of replication if the missing gene product is provided in trans. As a result, these viruses are restricted to specific cell lines, making them safe to handle at lower biosafety levels. Here, we provide a detailed overview of how to generate MARV in which the VP30 gene has been replaced by a green fluorescent reporter gene, as well as how to use lentiviral transduction to create stable cell lines expressing MARV VP30. These cell lines can be used for the propagation and confinement of the resulting reporter virus.

Wild-type Marburg virus (MARV) can only be handled in biosafety level 4 facilities. By removing an essential gene from the virus genome, deficient virus particles can be generated that are only capable of replication if the missing gene product is provided in trans. As a result, these viruses are restricted to specific cell lines, making them safe to handle at lower biosafety levels. Here, we provide a detailed overview of how to generate MARV in which the VP30 gene has been replaced by a green fluorescent reporter gene, as well as how to use lentiviral transduction to create stable cell lines expressing MARV VP30. These cell lines can be used for the propagation and confinement of the resulting reporter virus.
