|---|---|
| 商品货号： | TS158342 |
| Classification： | Poxviridae, Orthopoxvirus |
| Agent： | Vaccinia virus ts mutant |
| Strain： | IHD-W Dts56 |
| Applications： | Vaccination is recommended for laboratory staff manipulating vaccinia, monkeypox and cowpox viruses. It was not assigned to a Dales EM category (Dales, et al, 2003), but was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location D5, an ATPase required for DNA replication. |
| Biosafety Level： | 2 BSL 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 no. 7473, 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： | This vaccinia mutant, originally designated plaque isolate no. 7473, was isolated from the IHD-W strain of Vaccinia by S. Dales, presumably by mutagenesis with nitrosoguanidine followed by replication in the presence of bromodeoxyuridine. It was not assigned to a Dales EM category (Dales, et al, 2003), but was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location D5, an ATPase required for DNA replication. Shifting infection conditions from permissive to non-permissive temperature (39.5 C) results in an abrupt cessation of DNA synthesis, described as a "fast stop" phenotype.
Vaccination is recommended for laboratory staff manipulating vaccinia, monkeypox and cowpox viruses. |
| Effect on Host： | Cytopathic effects in culture include cell enlargement and rounding, followed by death and sloughing CPE: enlargement, plaques with rounding and eventual sloughing |
| Growth Medium： | ATCC® Medium 30-2003: Eagles Minimum Essential Medium (EMEM) Fetal Bovine Serum |
