A standardized protocol for the UV induction of Sulfolobus spindle‑shaped virus 1
Artikel i vetenskaplig tidskrift, 2015
The Fuselloviridae prototype member Sulfolobus
spindle-shaped virus 1 is a model of UV-inducible
viruses infecting Crenarchaeota. Previous works on SSV1
UV induction were bases on empirically determined parameters
that have not yet been standardized. Thus, in many
peer reviewed literature, it is not clear how the fluence and
irradiance have been determined. Here, we describe a protocol
for the UV induction of SSV1 replication, which is
based on the combination of the following instrumentally
monitored parameters: (1) the fluence; (2) the irradiance;
(3) the exposure time, and (4) the exposure distance. With
the aim of finding a good balance between the viral replication
induction and the host cells viability, UV-irradiated
cultures were monitored for their ability to recover in the
aftermath of the UV exposure. This UV irradiation procedure
has been set up using the well-characterized Sulfolobus
solfataricus P2 strain as model system to study host–
virus interaction.
