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 embryo
Strain NIH/Swiss
Applications This line is capable of packaging nucleic acids containing a psi packaging sequence into recombinant ecotropic retrovirus genomes. 

It can be used to produce retroviral vectors for delivery of foreign genes into susceptible eukaryotic cells.

This cell line is a suitable transfection host.

Storage Conditions liquid nitrogen vapor phase
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.
Derivation
The line was established by electroporation of two plasmids into NIH 3T3 cells. One plasmid contained the gag and pol regions of Moloney murine leukemia virus (Mo-MuLV), the other contained the env region of Mo-MuLV.
Complete Growth Medium Dulbecco's modified Eagle's medium with 0.015 mg/ml hypoxanthine, 0.25 mg/ml xanthine, and 0.025 mg/ml mycophenolic acid; 90% calf serum, 10%.
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.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.03% (w/v) EDTA solution to remove all traces of serum which contains trypsin inhibitor.
  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 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.
  6. Incubate cultures at 37°C.

Subcultivation Ratio: 1:5 to 1:10
Medium Renewal: Twice a week

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.
