Documentation

Biosafety Icon Biosafety Level 2

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.

Cells contain herpesvirus

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.

Genes expressed
Epstein-Barr nuclear antigen 1 (EBNA-1)
Comments

Expression of EBNA-1 permits episomal replication of expression vectors such as pDC406 that contain the EBV origin of replication. The cells can be used as host for expression of transfected DNA.

The line was derived from CV-1 (ATCC CCL-70) by transfection with a plasmid encoding Epstein Barr Virus nuclear antigen 1 (EBNA-1).

Technical information
ATCC Technical Services does not have technical information on patent deposits that are not produced or characterized by ATCC. Additional information can be found in the corresponding patent available from the patent holder or with the U.S. and/or international patent office.

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium
The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature
37°C
Handling procedure
HANDLING PROCEDURE FOR FROZEN CELLS

- Initiate culture as soon as possible upon receipt.

- Thaw by rapid agitation in 37°C water bath. Thawing should be rapid (within
40-60 seconds). As soon as the ice is melted, remove the ampule from the water
bath and immerse in 70% ethanol at room temperature. All of the operations from
this point on should be carried out under strict aseptic conditions.

- The cells are supplied in two different types of glass ampules. One is a
standard ampule, the neck of which must be scored with a sharp file that has
been immersed in ethanol. A definitive sharp nick about 1/8" in length on one
side is necessary. The second type is prescored and is identifiable by a gold
band around the ampule neck, and should not be scored with a file.

- Break the neck of the ampule between several folds of a sterile towel.

- Transfer the cell suspension and dilute it with the recommended culture
medium in a culture flask (see specific batch information above for dilution
ratio); incubate at 37°C with 10% CO2 in air atmosphere. Since it is important
to avoid excessive alkalinity of the medium during recovery of the cells, it is
suggested that the culture medium be placed into the culture flask, tube, etc.
and the pH be adjusted, as necessary, prior to the addition of the ampule
contents. Note that the bicarbonate content of the culture medium will
determine whether an atmosphere containing CO2 will be required.

- It is not necessary to remove the freezing additive. However, if desired, the
culture medium may be changed to remove the protective freezing additive
(dimethylsulfoxide) 24 hours after thawing. If it is desired that the freezing
additive be removed immediately, or that a more concentrated cell suspension be
obtained, centrifuge the above diluted suspension at approximately 125 x g for
10 minutes, discard the fluid and resuspend the cells with growth medium at the
dilution ratio given in the specific batch information above.

FLUID RENEWAL
Two times weekly.

SUBCULTURE PROCEDURE
Remove medium, add fresh trypsin (0.25%) - EDTA (0.03%) solution for 1-3
minutes. Remove, place culture at room temperature or incubate (37°C) until
cells detach. Add fresh medium, aspirate and dispense into new culture flasks.
Subcultivation ratio: 1:3 to 1:6.
Subculturing procedure
Protocol: Remove old medium, add fresh 0.25% trypsin solution for 2 to 3 minutes, remove trypsin and let culture stand for 5 to 10 minutes at room temperature. Add fresh medium, aspirate and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: Twice per week
Reagents for cryopreservation
Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
