WebFeb 15, 2024 · Description lox71 is an engineered recombination target site derived from the wild-type loxP site (the target site for the recombinase encoded by the cre locus of the bacteriophage P1 genome).

In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites. The terms are constructed upon the phrase "flanking/flanked by LoxP". Recombination between LoxP sites is catalysed by Cre recombinase. Floxing a gene allows it to be deleted (knocked out), translocated or inverted in a process called Cre-Lox recombination. The fl…
