Host Organism : Production host: BSC-40 (ATCCCRL-2761)Alternate hosts: MRC-5, BSC-1, HeLa, LLC-MK2
Incubation : For best results, plate cells 24-48 hours in advance in DMEM with 10% FBS at 37.0°C. Infect at 90-100% confluence using a multiplicity of infection (MOI) of about 1. Infect and incubate in DMEM supplemented with 2% FBS at 32.0°C for 1-3 days. Harvest cells and culture fluids when 100% of culture shows advanced cytopathic effects. Vaccinia virus is largely cell associated. Concentrated preparations can be made by collection and sonication of cell pellets.
Effect : Cytopathic effects in culture include enlargement and rounding of cells, followed by death and sloughing.
Store at : -70.0°C or colder
Comments : This conditional lethal mutant, originally designated plaque isolate number 9179, was isolated from the IHD-W strain of Vaccinia by S. Dales. The IHD-W strain was derived from an IHD-J strain. This mutant was selected after mutagenesis with nitrosoguanidine and replication in the presence of bromodeoxyuridine. This mutant was not assigned to a Dales EM category. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location A24, the 132-kDa RNA polymerase subunit. The non-permissive incubation temperature is 39.5°C. Vaccination is recommended for laboratory staff manipulating vaccinia, monkeypox, and cowpox viruses.
