Isolation: Isolation date: 1992
Applications: Lung surfactant proteins B and C were detected.
The cells secrete phospholipids in response to phorbol esters and ATP but not in response to forskolin.
This line was established in 1992 by Kathryn A. MLE 12细胞Wikenheiser from pulmonary tumors in a mouse transgenic for the SV40 large T antigen under the control of the promoter region of the human surfactant protein C gene.
Tumorigenic: Yes
Age: 5 month old
Gender: female
Comments: This line was established in 1992 by Kathryn A. Wikenheiser from pulmonary tumors in a mouse transgenic for the SV40 large T antigen under the control of the promoter region of the human surfactant protein C gene.
The cells express the mRNA for large T antigen.
Lung surfactant proteins B and C were detected.
The cells secrete phospholipids in response to phorbol esters and ATP but not in response to forskolin.
Propagation: ATCC complete growth medium: HITES medium supplemented with 2% fetal bovine serum
HITES medium with 2% fetal bovine serum is formulated at the ATCC as follows:
Dulbecco's medium : Ham's F12, 50:50 mix (ATCC 30-2006)
MLE 12细胞Insulin 0.005 mg/ml
Transferrin 0.01 mg/ml
Sodium selenite 30 nM
Hydrocortisone 10 nM
beta-estradiol 10 nM
HEPES 10 mM
L-glutamine 2 mM (in addition to that in the base medium)
fetal bovine serum 2%
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Subculturing: Protocol:
Remove and discard culture medium.
Briefly rinse the cell layer with 0.25% (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 1:5 to 1:10 is recommended
Medium Renewal: Twice per week
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Doubling Time: 7 to 9 hrs
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2006
