|---|---|
| 商品货号： | TS142811 |
| Classification： | Poxviridae, Orthopoxvirus |
| Agent： | Vaccinia virus ts mutant |
| Strain： | IHD-W Dts57 (Dales isolate 7526) |
| Applications： | The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location U14. |
| Positive for Mycoplasma： | No |
| Biosafety Level： | 2 CDC BMBL recommends vaccination. ref
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： | derived from existing strain |
| Product Format： | frozen |
| Storage Conditions： | -70°C or colder |
| Comments： | Selected after mutagenesis with nitrosoguanidine and replication in the presence of bromodeoxyuridine. The non-permissive incubation temperature is 39.5oC. This mutant was assigned to Dales EM category H indicating that it is a composite of groups D, E and F, with foci of viroplasm, DNA paracrystals, and abberant membranes with and without spicules. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location U14. |
| Effect on Host： | Yes, Cytopathic effect: Rounding and sloughing of infected cells CPE: enlargement, plaques with rounding and eventual sloughing |
| Recommended Host： | Recommended Host: BSC-40 (ATCC CRL-2761 |
| Growth Conditions： | Temperature: 31.0°C Duration: 1-3 days; For best results, cells should be 24 to 48 hours old and 80-90% confluent at time of infection not 100% confluent. |
