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.

Detailed product information

Characteristics

Comments
VR-1438 is a mycoplasma-free strain of Mumps derived at the ATCC® from VR-365 by three passages in the presence of MP Biomedicals Mycoplasma Removal Agent, (4-oxoquinoline-3-carboxylic acid derivative). The most accurate method of titration to confirm infectivity endpoint is the hemadsorption technique. The Jones strain was passaged extensively in CE and CE TC to attenuate it for humans.
Mycoplasma contamination
Not detected

Handling information

Host
Host Range: chicken embryo fibroblasts; human kidney cells; marmoset kidney cells; rhesus monkey kidney cells; HEp-2 cells (ATCC CCL-23)
Effects
cell degeneration; cell sloughing; CPE
Complete medium
EMEM (ATCC® 30-2003™) + 10% FBS (ATCC® 30-2020™) + 1% NEAA + 10 mM HEPES
Temperature
37°C
Atmosphere
95% Air, 5% CO2
Incubation
5 to 7 days at 37°C, a 5% CO2 in air atmosphere is recommended
