The 705-Cre plasmid is designed for use in Cre-mediated genomic manipulations. The plasmid has a pSC101 origin which maintains low copy and replicates at 30Degree C. The plasmids will not propagate and will get lost when incubated at 37Degree C.
The expression of the Cre-recombinase is driven by the thermosensitive promoter cI578 (?PR promoter). Therefore, the expression of Cre is repressed at 30Degree C and induced between 37-42Degree C. The plasmid carries a chloramphenicol resistance.
