Vaccinia virus ts mutant (ATCC® VR-3131)

Classification: Poxviridae, Orthopoxvirus  /  Product Format: frozen

Classification Poxviridae, Orthopoxvirus
Agent Vaccinia virus ts mutant
Strain IHD-W Dts9
Applications
The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location D13, which encodes a 65-kDa protein thought to function as a scaffold protein for the formation of viral crescents and immature virions.
Biosafety Level 2 BSL 2Vaccination is recommended for laboratory staff working with vaccinia, monkeypox and cowpox viruses
Isolation
This conditional lethal mutant, originally designated plaque isolate no. 1085, was isolated from the IHD-W strain of Vaccinia by S. Dales. The IHD-W strain was derived from an IHD-J strain of Vaccinia.
Product Format frozen
Storage Conditions -70°C or colder
Comments
Selected after mutagenesis with nitrosoguanidine. The non-permissive incubation temperature is 39.5 C. This mutant was assigned to Dales EM category E, inducing foci of viroplasm, aberrant membranes without spicules, and DNA paracrystals in infected cells. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location D13, which encodes a 65-kDa protein thought to function as a scaffold protein for the formation of viral crescents and immature virions.
