IEC-18 ( CRL-1589™)

Organism: Rattus norvegicus, rat / Cell Type: epithelial / Tissue: ileum /
Organism Rattus norvegicus, rat
Tissue ileum
Cell Type epithelial
Product Format frozen
Morphology epithelial
Culture Properties adherent
Biosafety Level 1
Derivation
IEC-18 was derived from epithelial cells from rat small intestine.
Complete Growth Medium Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose and supplemented with 0.1 Unit/ml bovine insulin, 95%; fetal bovine serum, 5%
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.

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 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 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 1:6 is recommended
Medium Renewal: Twice per week
Cryopreservation
Freeze medium: culture medium 82.5%; fetal bovine serum 10%; DMSO 7.5%
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
