Documentation

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Characteristics

Comments
Add contents of thawed ampule to a 80-85% monolayer of HDF cells. If foci of CPE fail to spread by day 11 PI, split infected cells 1:2 and observe for CPE as monolayer reforms.
Attenuated for man, broad antigenicity. Stable for 6 months at -60°C in form of glycerinated cells. Virus primarily cell associated. A long (10-11 day) incubation is required for initial passage of frozen stocks.
Mycoplasma contamination
Not detected

Handling information

Host
Effects
cell rounding; cell sloughing; CPE
Complete medium
EMEM (ATCC 30-2003) + 10% FBS (ATCC 30-2020)
Temperature
37°C
Atmosphere
95% Air, 5% CO2
Incubation
2-7 days in a 5% CO2 air atmosphere in a stationary position until CPE is seen
Recommendation for infection
Trypsinize a 2-4 day old cell culture and seed at a density of 105 cells per cm2 (2.5x106 cells/T25 flask; 7.5x105 cells per T75 flask) using the virus growth medium (VGM). To the freshly trypsinized cells inoculate using a MOI of 0.1. Immediately add additional VGM depending upon the size of the flask used (recommended medium volume for T25 is 5 to 7 mL and for T75 15 to 22.5 mL). Incubate for 24 hours at 37°C in a 5% CO2 atmosphere. Aspirate media and add fresh virus/cell growth medium to remove any traces of DMSO. Continue incubation.
