ID MB19tsA clone 2B2 AC CVCL_6500 SY Mbeta19tsA clone 2B2; Mbeta19tsA, clone 2B2 DR CLO; CLO_0007554 DR ATCC; CRL-2308 DR Wikidata; Q54904103 RX PubMed=8538772; CC Characteristics: Deficient in base excision repair due to homozygous deletion of the promoter and exon 1 of polB. The deletion of polB is mediated by the Cre-loxP recombination. This deletion event is reversible and therefore this cell line is ideal for site-specific recombination using the Cre-lox system (ATCC=CRL-2308).
