Webcre is the recombinase enzyme (derived from a P1 bacteriophage) which in a given line of mice is under the control of a specific promoter. The promoter dictates when during development and/or where within tissues the recombinase will be expressed. "Floxed" is shorthand for flanked by LoxP sites, which is what you do to your target gene. WebConditional knockout mice are usually generated using Cre-LoxP, Dre-Rox or Flp-Frt recombination systems for permanent gene alterations in specific tissues. A conditional knockout (cKO) model is generated via several steps, using Cre-LoxP system as an example: The targeted fragment to be knocked out is flanked by LoxP elements. hbv populationWebThe homozygous Tsc2(flox/flox) mice are identical to wildtype in many organs typically affected by TSC, especially the brain. Using this Tsc2(flox) allele we have generated a null allele using Cre recombination.

Cre-Lox recombination is a site-specific recombinase technology, used to carry out deletions, insertions, translocations and inversions at specific sites in the DNA of cells. It allows the DNA modification to be targeted to a specific cell type or be triggered by a specific external stimulus. It is implemented both in eukaryotic and prokaryotic systems.
