|---|---|
| 商品货号： | TS213562 |
| Classification： | Poxviridae, Orthopoxvirus |
| Agent： | Vaccinia virus ts mutant |
| Strain： | IHD-W Dts86 |
| Applications： | The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location A24, the 132-kDa RNA polymerase subunit. Vaccination is recommended for laboratory staff manipulating vaccinia, monkeypox, and cowpox viruses. |
| Biosafety Level： | 2
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Isolation： | 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. |
| Product Format： | frozen |
| Storage Conditions： | -70°C or colder |

| Effect on Host： | CPE: enlargement, plaques with rounding and eventual sloughing Cytopathic effects in culture include enlargement and rounding of cells, followed by death and sloughing. |
| Growth Medium： | ATCC® Medium 30-2002: Dulbeccos Modified Eagles Medium (DMEM) Fetal Bovine Serum |
| Recommended Host： | Recommended Host: xa0BSC-40 (ATCC CRL-2761) Production host: BSC-40 (ATCC CRL-2761)
Alternate hosts: MRC-5, BSC-1, HeLa, LLC-MK2 |
| Growth Conditions： | 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. |
