WebJun 1, 2024 · The Lox or loxP sites (locus of X over P1) are the palindromic sites recognized by cre-recombinase. Each site is 13 bp long, and an 8 bp spacer region separates the two sites. DNA sequences found between … 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…
