Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimately responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.

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

Subculturing: Protocol: The cells should be subcultured before reaching confluence.

Remove medium, add fresh 0.05% trypsin - 0.53 mM EDTA, rinse and remove trypsin. Allow the culture sit at room temperature (or 37C) until the cells detach. 2.040 pRSV-T細(xì)胞Neutralize the trypsin with fresh 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 (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

Subcultivation Ratio: Subculture at 1:3 when 80% confluent.

Medium Renewal: Every 2 to 3 days

Preservation: Freeze medium: Complete growth medium, 82.5%; DMSO, 7.5%

Storage temperature: liquid nitrogen vapor phase
