| Disclosure： | This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC. |
| Derivation： | PG13 is a retrovirus packaging cell line derived from TK- NIH/3T3 cells and based on the Gibbon ape leukemia virus (GaLV). |
| Comments： | Introduction of retroviral vectors by infection or transfection results in the production of retrovirus virions capable of infecting cells from many species (with the exception of mice). Selection against loss of the DNAs conferring the packaging functions can be performed by growing the cells in medium containing dialyzed fetal bovine serum and 100 nM amethopterin for 5 days followed by cultivation in medium containing HAT and untreated fetal bovine serum for an additional 5 days.After selection, the cells should be maintained in medium containing HT for 2 days to avoid toxic effects due to residual amethopterin. A derivative of this line is available (PG13/LN c8, see ATCC CRL-10685) that produces a neomycin resistance transducing vector. Although virus production has not been observed, there is a possibility that the cells will produce a virus similar to GaLV (a moderate risk oncogenic virus) and Biosafety Level 2 or higher precautions should be taken when using this cell line. |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles 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%.
|
| Subculturing： | Protocol: Remove medium, add fresh 0.25% Trypsin, 0.53 mM EDTA solution and allow the flask to sit at room temperature (or 37C) until the cells detach (2 to 3 minutes). Add fresh medium, aspirate and dispense into new flasks. Subcultivation Ratio: A subcultivation ratio of 1:8 is recommended Medium Renewal: Every 2 to 3 days |
| Cryopreservation： | Freeze medium: Complete growth medium, 95%; DMSO, 5%. Cell culture tested DMSO is available as ATCC Catalog No. 4-X. |
| Culture Conditions： | Temperature: 37°C |
