- original paper: Broad-host-range cre-lox system for antibiotic marker recycling in gram-negative bacteria. Marx (2002)
- sequence: (addgene)
Not shown: Cre recombinase site, useful for curing antibiotic via pCM157.
Advice: if possible, remove the repetitive sequence (cccccccccccc/gggggggggggg) between the up/down stream regions and the recombination site recognized by pCM157: causes Sanger sequencing to hiccup.
