lox66

lox66 is a site specific recombination cassette. It belongs to the loxP family frequently used in genetics, particularily in mouse genetics. lox site recombination is catalysed by a Site specific recombinase, Cre. lox sequences are composed of an 8 bp Core sequence surrounded by two Arms. The particularity of lox66 is that it has an altered sequence at the end of it's left arm compared to loxP. This sequence variation reduces affinity of the Cre recombinase for the arm. As a consequence, after a recombination between a lox66 and a lox71 (altered right arm sequence), one of the two resulting generated lox sites has very low recombination potential as it inherited both mutated arms.
