Biosafety Level
2  [Cells contain SV-40 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.

Age
10.5 days gestation
Gender
female
Applications
The cell line is an isogenic, wild-type line to be used in concert with the base excision repair deficient cell line, MBl9tsA, clone 2B2 (ATCC CRL-2308).
Storage Conditions
liquid nitrogen vapor phase
Derivation
MB16tsA, clone 1B5 is a fibroblast-like cell line derived from primary cultures of wild-type cells isolated from embryos from heterozygous females (beta-polymerase +/-) at day 10.5 of gestation.
Comments
The wild-type fibroblasts were immortalized by transfection with the DNA plasmid construct ptsA58H which contains coding sequences for both a hygromycin-resistance gene and tsA58H, a temperature-sensitive SV40 T antigen.
Cells were selected in the presence of 0.080 mg/ml hygromycin for 21 days and further selected by limiting dilution.
The cell line is an isogenic, wild-type line to be used in concert with the base excision repair deficient cell line, MBl9tsA, clone 2B2 (ATCC CRL-2308).
Complete Growth Medium
Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and supplemented with 0.08 mg/ml hygromycin B, 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).
    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 34°C.

Subcultivation Ratio: 1:10 to 1:15
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
