Cre Mouse/Rat Models

Researchers use gene-edited mouse models to study gene expression, investigate genetic diseases, conduct preclinical drug efficacy tests and more. In many studies, a mouse model expresses a gene mutation throughout its development and life, necessitating an inducible disease mouse model when researchers need more control over gene expression.

Mouse models that provide this level of control are called conditional mouse models, of which one of the most effective is the Cre/Loxp mouse. Cre mice express Cre recombinase under the control of a tissue specific gene promoter, i.e. Cre mouse lines provide the tissue specificity of gene editing. If CreERT2 instead of Cre is used, then the DNA recombinase activity is induced by Tamoxifen, so that the Cre/Loxp mouse model will be conditional and inducible. The LoxP mouse line has two loxP elements flanking the entire or part of the gene of interest, giving the loxP mouse defined gene(s) to be edited.

The Cre-Lox system is an efficient method for producing conditional mouse models. At Biocytogen, we provide custom Cre-Lox mouse models for use in academic and pharmaceutical research. We can design a Cre mouse model, conduct research and deliver results in as little as nine months. Fill out a form or contact us today to learn more.
