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： | Dulbeccos modified Eagles 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.
