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.

Gender
female
Applications
xrs5 is a X-ray sensitive Chinese Hamster Ovary mutant cell line which was derived from CHO-K1 cells by treating the cells with ethyl methanesulphonate and subsequent growth in agar.
Storage Conditions
liquid nitrogen vapor phase
Derivation

Clinical Data
female
Comments
xrs5 is a X-ray sensitive Chinese Hamster Ovary mutant cell line which was derived from CHO-K1 cells by treating the cells with ethyl methanesulphonate and subsequent growth in agar.
These cells belong to X-ray complementation group 5 and are mutant in the p86 subunit of the Ku autoantigen.
Ku has been shown to be involved in DNA double-strand break repair and V(D)J recombination.
The cells will revert to wild type on treatment with azacytidine.
Complete Growth Medium
Alpha minimum essential medium without ribonucleosides and deoxyribonucleosides with 2 mM L-glutamine, 90%; fetal bovine 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-0.53mM 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).
  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: 1:6 to 1:10
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.

Cryopreservation

Complete growth medium described above supplemented with 5% (v/v) DMSO.  Cell culture tested DMSO is available as ATCC Catalog No. 4-X.

Culture Conditions
Temperature: 37°C
Atmosphere: Air, 95%; Carbon dioxide (CO2), 5%
