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 … See more Floxing a gene allows it to be deleted (knocked out), translocated or inserted (through various mechanisms in Cre-Lox recombination).
