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.

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%.
95% Air, 5% CO2
Handling procedure

- 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. All of the operations from this point on should be carried out under
strict aseptic conditions.

- 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 vial
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.

Add fresh medium (depending on cell density) every 2-3 days.

Cultures can be maintained by the addition of fresh medium or the replacement
of medium. Alternatively cultures can be established by centrifugation with
subsequent resuspension at 1-2 x 10(5) viable cells/ml. Maintain cell culture
density between 10(5) and 10(6) viable cells/ml.
Subculturing procedure
Protocol: Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 to 2 X 10(5) viable cells/ml.
Subcultivation Ratio: Maintain cell density between 1 X 10(5) and 1 X 10(6) viable cells/ml.
Medium Renewal: Every 2 to 3 days
Reagents for cryopreservation
Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
