Vaccinia virus ts mutant (ATCC® VR-3121)

Classification: Poxviridae, Orthopoxvirus  /  Product Format: frozen

Classification Poxviridae, Orthopoxvirus
Agent Vaccinia virus ts mutant
Strain IHD-W Dts8 (Dales isolate 991)
Applications
The non-permissive incubation temperature is 39.5oC. This mutant was assigned to Dales EM category L indicating that it produces immature particles with nucleoids and defective membranes with spicules.
The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location U5.
Positive for Mycoplasma No
Biosafety Level 2
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 L indicating that it produces immature particles with nucleoids and defective membranes with spicules. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location U5.
