Isolation: The STO cell line was derived by A. Bernstein, Ontario Cancer Institute, Toronto Ontario, Canada from a continuous line of SIM mouse embryonic fibroblasts.
Applications: transfection host
Age: embryo
Comments: STO细胞The STO cell line was derived by A. Bernstein, Ontario Cancer Institute, Toronto, Canada from a continuous line of SIM mouse embryonic fibroblasts. The population which was selected for 6-thioguanine and ouabain resistance is sensitive to HAT medium and is HPRT negative. The cell line is used routinely to prepare feeder layers by irradiation or mitomycin C treatment. Such populations are then employed for maintenance of stock teratocarcinoma stem cells (see ATCC CRL-1535 and CRL-1566) in the undifferentiated state.The cells have been tested and found negative for ectromelia virus (mousepox).
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: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Protocol:
Remove and discard culture medium.
Briefly rinse the cell layer with 0.25% STO细胞(w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37�C to facilitate dispersal.
Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
Add appropriate aliquots of the cell suspension to new culture vessels.
Incubate cultures at 37�C.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:10 is recommended
Medium Renewal: 2 to 3 times per week
