How are knockout mice created

WebA conditional knockout allele can be created using Cre/Lox technology, which involves inserting Lox sites to flank an essential exon or exons in a gene. The conditional knockout mice are phenotypically wild type but contain the ‘floxed’ allele in all tissues. Cre recombinase then excises the DNA between two Lox sites resulting in a non ... WebTargeted mutant mice are produced by first inducing gene disruptions, replacements or duplications into embryonic stem (ES) cells via homologous recombination between the exogenous (targeting) DNA and the endogenous (target) gene. The genetically modified ES cells are then microinjected into host embryos at the eight-cell blastocyst stage.
