Tested Positive for Mycoplasma : No
Incubation : Atmosphere: 5% CO2 in air recommended Temperature: 31.0°C Duration: 1-3 days; For best results, cells should be 24 to 48 hours old and 80-90% confluent [not 100% confluent] for inoculation.
Effect : Yes, Cytopathic effect: Rounding and sloughing of infected cells
Store at : -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 a Dales EM category of P, characterized by immature normal particles and mature particles with cores that are predominantly lucent at the center. The mutation was assigned by complementation analysis (Lackner, et al, 2003) to vaccinia map location U12.
