Organism Canis familiaris, dog
Tissue kidney; distal tubule
Product Format frozen
Morphology fibroblast-like
Culture Properties adherent
Biosafety Level 1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Age adult
This cell line is insensitive to epsilon toxin from C.perfringens and is a control for MDCK.2 (ATCC CRL-2936)
Storage Conditions liquid nitrogen vapor phase
Karyotype hyperdiploid canine cell line with a modal chromosome number of 76 with low polyploidy rate. Several unidentifiable marker chromosomes were present in most of the cells examined.
Cell line was derived by cloning (limited dilution) the parental cell line MDCK (ATCC CCL-34)
Antigen Expression
E-cadherin (epithelial cell adhesion molecule), expressed
Zona Occludens (ZO-1) (tight junction protein), not expressed
CD29, expressed
CD18, not expressed
fibroblast-specific protein (FSP), not expressed
cytokeratin (CK1, 4, 5, 6, 8, 10, 13, 18, 19),expressed
Complete Growth Medium The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. 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.
  3. Add 1.0 to 2.0 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. An inoculum of 1 X 104 to 3 X 104 viable cells/cm2 is recommended.
  6. Incubate cultures at 37°C. Subculture when the cell concentration is between 8 X 104 and 2 X 105 cells/cm2.

Subcultivation ratio: A subcultivation ratio of 1: 3 to 1:8 is recommended.
Medium renewal: Every 2 to 3 days.

Freeze medium: Complete growth medium, 95%; DMSO, 5%
liquid nitrogen vapor phase
Population Doubling Time approximately 14 hours
