Vaccinia virus ts mutant (ATCC® VR-3144)

Classification: Poxviridae, Orthopoxvirus  /  Product Format: frozen

Classification Poxviridae, Orthopoxvirus
Agent Vaccinia virus ts mutant
Strain IHD-W Dts20 (Dales isolate 2160)
Applications
The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location.
Positive for Mycoplasma No
Biosafety Level 2 CDC BMBL recommends vaccination.
Isolation
derived from existing strain
Product Format frozen
Storage Conditions -70°C or colder
Comments
Selected after mutagenesis with nitrosoguanidine. The non-permissive incubation temperature is 39.5oC. This mutant was assigned to Dales EM category P, characterized by immature normal particles and mature particles with cores that are predominantly lucent at the center. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location.
Effect on Host
Yes, Cytopathic effect: Rounding and sloughing of infected cells
CPE: enlargement, plaques with rounding and eventual sloughing
Recommended Host

Recommended Host: BSC-40 (ATCC CRL-2761

This mutant strain was derived by Samuel Dales from the IHD-W strain of Vaccinia (ATCC VR-1441) which in turn was derived from the IHD-J strain.
