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.

Detailed product information


Specific applications
Enteric Research


Derived by passage of ATCC VR-784 in Vero cells (ATCC CCL-81). This product replaces ATCC VR-784 and exhibits CPE when cells are infected.
Note: The sequences of ATCC VR-784 and ATCC VR-1775 have not been compared.
Mycoplasma contamination
Not detected

Handling information

CPE; cell degeneration; cell rounding; cell sloughing
Complete medium
EMEM (ATCC 20-2003) + 2% FBS (ATCC 30-2020)
95% Air, 5% CO2
Incubate infected culture for 5-9 days at 37°C in a humidified 5% CO2 atmosphere, until CPE are well advanced through 90% of the culture.
Recommendation for infection
Plant cells 24-48 hours in advance and infect when cultures are 70-80% confluent. Remove medium, wash cell monolayer once with PBS, and inoculate with a small volume (eg. 1 mL per cm2) of virus diluted to provide a MOI of about 0.1. Adsorb 1-2 hours at 37°C in a humidified 5% CO2 atmosphere. End adsorption by adding virus growth medium.
Handling notes
Derived by passage of ATCC VR-784 in Vero cells (ATCC CCL-81). This product will replace ATCC VR-784.  (Note:  The sequences of ATCC VR-784 and ATCC VR-1775 have not been compared).
