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. |
| Disease |
malignant glioblastoma; glioma |
| Age |
33 years |
| Gender |
male |
| Applications |
Together, M059K and M059J provide a useful model system in which to study the role of DNA protein kinase in cellular and molecular processes involving DNA damage recognition and repair |
| Storage Conditions |
liquid nitrogen vapor temperature |
| Karyotype |
aneuploid; Y chromosome is present |
| Derivation |
M059J cells were isolated from a tumor specimen taken from a 33 year old male with untreated malignant glioblastoma The cells were isolated concurrently from the same tumor specimen as M059K (see CRL-2365). |
| Clinical Data |
male
33 years |
| Comments |
M059J cells lack DNA-dependent protein kinase activity, while M059K cells express normal levels of DNA-dependent protein kinase. M059J cells are approximately 30-fold more sensitive to ionizing radiation than M059K cells. M059J cells are more sensitive than M059K cells to the cytotoxic effects of bleomycin, N,N-bis(2-choroethyl)-N-nitrosourea and nitrogen mustard. M059J cells are deficient in repair of DNA double strand breaks. The cells are negative for glial fibrillary acidic protein (GFAP). |
| Complete Growth Medium |
These cells are grown in a medium containing a 1:1 mixture of Dulbecco's Modified Eagle's Medium and Ham's F12 medium with 2.5 mM L-glutamine adjusted to contain 15 mM HEPES, 0.5 mM sodium pyruvate, and 1.2 g/L sodium bicarbonate supplemented with 0.05 mM non-essential amino acids and 10% fetal bovine serum.

| 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.
- Remove and discard culture medium.
- Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
- 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.
- Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
- Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C
Subculture Ratio: 1:6 to 1:8
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.
