Organism Rattus norvegicus, rat
Tissue
aorta, thoracic/smooth muscle
Product Format frozen
Morphology fibroblast
Culture Properties adherent
Biosafety Level 1
Age embryo
Strain DBIX
Applications
This cell line is a suitable transfection host.
Storage Conditions liquid nitrogen vapor phase
Images
Genes Expressed
myokinase; creatine phosphokinase (muscle isoenzyme); myosin
Cellular Products
myokinase; creatine phosphokinase (muscle isoenzyme); myosin
Comments
The cells exhibit an increase in activity of the enzymes myokinase and creatine phosphokinase (CPK) as the culture reaches stationary phase.
Muscle type CPK is synthesized after cell division has ceased.
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%.
Subculturing
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. 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.
  3. 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.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:3 is recommended
Medium Renewal: Every 2 to 3 days
Cryopreservation
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
Name of Depositor W Carlisle
