What are Cre lox mice?
The Cre/lox system is one of the most powerful and versatile tools developed for mouse genetics. It gives mouse researchers sophisticated control over the location and timing of gene expression. Cre/lox is usually used to make knockout alleles, but it can also be used to activate gene expression.
What are Flox mice?
With the Cre-lox system, developed and perfected over the course of the 1990s and 2000s, floxed mice have become a major tool for genetic researchers. They use these mice to study, document and understand diseases and the possible cures and treatments they might develop in order to counter them.
What is Dre recombinase?
Dre recombinase, like Cre, is a highly efficient site-specific recombinase in E. coli, mammalian cells and mice. Dis Model Mech.

How are Cre lox mice generated?
In general, Cre/lox mice are generated by mating a Cre-driver mouse with a flox mouse.
What is Rosa26 locus?
Known in scientific circles as Gt(ROSA)26Sor, the Rosa26 locus is a specific genetic site that is located on mouse chromosome 6, and is considered to be one of the ideal locations where knock-ins of interest can be targeted.
What is the genotype of a mouse?
The genotype for a specified gene in a mouse can be homozygous, heterozygous, wild type, and sometimes hemizygous (such as X-linked genes or transgenes). You may even have multiple genes with multiple genotypes in one mouse. The genotype of your mouse determines the phenotype.
How many genes does a mouse have?
Mice and humans each have about 30,000 genes, yet only 300 are unique to either organism.
What is lox stop lox?
Cre-dependent gene expression – placing a stop codon with loxP sites on either side (often called a “lox-stop-lox” or “LSL” cassette) upstream of a gene of interest will prevent gene expression in the absence of Cre. In the presence of Cre, the stop codon is excised, and gene expression proceeds.
What is the function of Cre?
The Cre protein is a site-specific DNA recombinase that can catalyse the recombination of DNA between specific sites in a DNA molecule. These sites, known as loxP sequences, contain specific binding sites for Cre that surround a directional core sequence where recombination can occur.
How do you know if you have been floxed?
Signs + Symptoms Mitochondrial dysfunction and DNA damage. Brain Fog. Peripheral Neuropathy. Blurry Vision.
How does Flox Cre work?
General principle of Cre-loxP system Concerning the mechanism of Cre-loxP system, a single Cre recombinase recognizes two directly repeated loxP site, then the Cre excises the loxP flanked (floxed) DNA, thus creating two types of DNA with circular, excised and inactivated gene Y (Figure 1A).
What is GT Rosa 26Sor?
The Gt(ROSA)26Sor locus (ROSA26) was first described as a gene trap which is ubiquitously expressed in mouse embryos [15]. As the ROSA26 locus is active in most cells any promoter inserted into the locus should not be restricted in its expression by unfavourable chromatin configurations.
What is the AAVS1 locus?
The adeno-associated virus site 1 (AAVS1) locus in the human genome is a strong candidate for gene therapy by insertion of an exogenous gene into the locus. The AAVS1 locus includes the coding region for myosin binding subunit 85 (MBS85).
How do you write a genotype for a mouse?
Thus, we designate our mouse genotypes “-/-” for homozygous mutants, “+/-” for heterozygotes, and “+/+” for wildtypes.
