Strain developmentThis strain was developed for efficient detection of mutations in vivo by Dr.Nohmi T.
Strain descriptionThis strain is useful to detect point mutations and deletions with high efficiency and sensitivity in vivo. The mice carry lambda EG10 DNA as a transgene. When the rescued phages are infected into Escherichia coli YG6020-expressing Cre recombinase, the phage DNA is converted into plasmid pYG142 carrying the chloramphenicol-resistance gene and the gpt gene of E. coli. The gpt mutants can be positively detected as colonies arising on plates containing chloramphenicol and 6-thioguanine. The EG10 DNA carries a chi site along with the red and gam genes so that the wild-type phages display Spi-(sensitive to P2 interference) phenotype. Mutant phages lacking both red and gam genes can be positively detected as plaques that grow in P2 lysogens of E. coli.
