Age: fetus
Comments: 2A細胞The 2A amphotropic retroviral packaging cell line was derived from the human embryonic kidney line, 293 (see ATCC CRL-1573).
293 cells were co-transfected with the methotrexate resistance vector, pFR400 and the MoMLV gag/pol expression vector, pSCV10. [57428]
After selection for transfected cells, individual drug resistant cell colonies were expanded, analyzed and selected for overexpression of MoMLV gag/pol. [57428]
293 (clone 2-3) was co-transfected with the phleomycin resistance vector, pUT507 and the amphotropic envelope expression vector, pMLPenvAmSph and subsequently cloned. [57428]
The 2A clone was selected for expression of relatively high levels of both gag/pol and amphotropic envelope proteins. [57428]
Propagation: ATCC complete growth 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:
O.1 mM Non-Essential Amino Acids (NEAA)
fetal bovine serum to a final concentration of 10%
2A細胞Temperature: 37.0°C
Subculturing: Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended
Medium Renewal: Every 2 to 3 days
Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Preservation: culture medium 95%; DMSO, 5%
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2002
recommended serum:ATCC 30-2020
parental cell line:ATCC CRL-1573
