Comments: The F2 subclone of AtT-20 (see ATCC CCL-89) was developed by B. Gumbiner.
This clone has been been used successfully by Moore et al. for several DNA mediated transfection studies relating to endocrine and exocrine secretory pathways.
The cells are readily transfected using a standard calcium phosphate protocol.
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%.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Subculturing: Protocol:
Cells grow in patches and pile up. Cultures do not become confluent.
AtT-20/D16v-F2细胞Volumes used in this protocol are for 75 sq cm flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Remove and discard culture medium.
Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS) or 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which 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 minutes).
Note: Extreme care must be taken to prevent the cells from clumping. Carefully follow the subcultivation protocol .do not over trypsinize. The cells will slough if the pH of the medium becomes too acidic (lower than 7.5).
Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
Transfer cell suspension to a centrifuge tube and spin at approximately 125 xg for 5 to 10 minutes. Discard supernatant.
Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels.
Incubate cultures at 37C.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:5 is recommended
Medium Renewal: Three times weekly
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
