產(chǎn)品名稱 2.040 pRSV-T
商品貨號(hào) B161389
Organism Homo sapiens, human
Tissue eye, cornea
Cell Type epithelial; transfected with a plasmid containing the SV40 early region
Product Format frozen
Morphology epithelial
Culture Properties adherent
Biosafety Level 2  [Cells contain SV-40 and Rous Sarcoma viral sequences]

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.

Disclosure This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC.
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.
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.
Subculturing

Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

Note: The flasks used should be precoated with a mixture of 0.01 mg/mL fibronectin, 0.03 mg/mL bovine collagen type I and 0.01 mg/mL bovine serum albumin. Subculture when 80% confluent.

  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.05% Trypsin – EDTA (GIBCO cat# 25300-054).
  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 with 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  fresh medium and aspirate cells by gently pipetting. 
  5. To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to10 minutes.
  6. Discard supernatant and resuspend cells in fresh growth medium.  Add appropriate aliquots of cell suspension to new coated culture vessels. 
  7. Place culture vessels in incubators at 37°C.

Subcultivation Ratio: 1:3
Medium Renewal: Every 2 to 3 days.

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.

Culture Conditions
Temperature: 37°C
