Plasmid encoding the full-length anti-genome of Marburg virus strain Musoke under the control of the T7 polymerase for rescue experiments. The plasmid contains two genetic markers: insertion of a SacII restriction site in the GP gene (nt position 10511a to g silent mutation) and a silent mutation at nt position 9485 c toT in the GP gene resulting in the deletion of a KpnI restriction site
