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
General
- Specific applications
-
Animals were immunized with BB2800 leukemia cells which produce both Friend MuLV (FrMuLV) and mink cell focus inducing (MCF) FrMuLV.The antibody neutralizes most MCF and polytropic MuLV, and reacts well with live or fixed infected cells and with Western blots.The antibody efficiently immunoprecipitates gp70, and can be used to distinguish polytropic MuLV from ecotropic, xenotropic and amphotropic MuLV.

Handling information
- Unpacking and storage instructions
-
- Check all containers for leakage or breakage.
- 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 DMEM:F12 Medium (ATCC 30-2006). To make the complete growth medium, add the following components to the 500 mL of the base medium:
- 10% fetal bovine serum (FBS; ATCC 30-2020)
- 10 µg/mL insulin
- 5.5 µg/mL transferrin
- 5 ng/mL selenium
- 10 ng/mL EGF
- 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.
- Transfer the cell suspension and dilute ampule contents wiit culture medium
(see specific batch information above for dilution ratio). Centrifuge 1000 rpm
for 10 minutes. Resuspend and plate 1/5 of cells into one 25 cm. sq. and 4/5 of
cells into another 25 cm. sq. flask, each with 7-10 ml of culture medium
containing 0.5 to 1 x 10(6) mouse spleen cells/ml. Incubate at 37°C with 5% 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 xg for
10 minutes, discard the fluid and resuspend the cells with growth medium at the
dilution ratio given in the specific batch information above.
- Subculturing procedure
-
Medium Renewal: Every 2 to 3 daysCultures can be maintained by addition or replacement of fresh medium. Start cultures at 2 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml.
