| Derivation: | MB355 (Polb/p53 double null) is a mouse embryonic fibroblast (MEF) cell line derived from polymerase (DNA directed), beta (Polb)/p53 double null embryos at day 14.5 of gestation. The cells were spontaneously immortalized at passage 5 due to the loss of the p53 gene. The cells are transgenic for lambda LIZ (Lac I/cII). |
