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). The floxing of genes is essential in the development of … See more Cardiomyocytes (heart muscle tissue) have been shown to express a type of Cre recombinase that is highly specific to cardiomyocytes and can be used by researchers to … See more Webfloxed allele. What floxed means? Floxing is the introduction of specific sequences, on either side of a targeted gene, that ultimately can lead to deletion of the intervening sequences in the presence of CRE recombinase.
