Comments:A primary culture of normal corneal epithelium was immortalized by transfection with plasmid pRSV-T using lipofectamine overnight at 37C. pRSV-T contains the SV40 early region genes and the Rous Sarcoma virus long terminal repeat.
Propagation:
ATCC complete growth medium: Keratinocyte-Serum Free medium (GIBCO-BRL 17005-042) with 5 ng/ml human recombinant EGF, 0.05 mg/ml bovine pituitary extract, 0.005 mg/ml insulin and 500 ng/ml hydrocortisone.
Temperature: 37.0°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Subculturing:
Protocol:Subculture when 80% confluent
-
remove medium
-
briefly rinse the cell layer with 0.05% (w/v) Trypsin-53mM EDTA solution
-
add Trypsin-EDTA solution to flask and incubate at 37?C for up to three minutes to facilitate dispersal. Observe cells under an inverted microscope. Hit or shake the flask if some cells remain attached
-
neutralize the trypsin with growth medium, centrifuge at 300 x g for 8 minutes
-
resuspend the pellet in fresh growth medium and dispense into new COATED flasks. Flasks used to propagate these cells must be coated (for at least 2 hours at 37C) with 0.01 mg/ml bovine serum albumin, 0.01 mg/ml fibronectin and 0.03 mg/ml bovine collagen type I.
-
Incubate at 37C with 5% CO2. Cells will not be well attached for the first 24 hours after subculture.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended when 80% confluent
Medium Renewal: Every 2 to 3 days
Preservation:
Freeze medium: complete growth medium supplemented with 7.5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
