Flox flox cre system
WebA liver-specific SphK1 gene knockout mouse model was constructed by the Cre/Loxp recombinant enzyme system. PCR technologies and western blotting were used to identified the elimination of SphK1 gene in hepatocytes. ... SphK1 flox/flox mice were used as a control group to verify the effectiveness of SphK1 liver-specific knockout mice from … 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 scientific model systems as it allows spatial and temporal alteration of gene expression. In layman's terms, the gene can be knocked-out (inactivated) in a specific tissue in vivo, a…
