WebMost mouse geneticists who work with Cre-lox mice probably are familiar with the FLP-FRT system. Like Cre, FLP is a tyrosine recombinase, but it originates from the yeast Saccharomyces cerevisiae, rather than from bacteriophage. In FLP-FRT, FLP is analogous to cre and FRT to loxP – FLP recognizes the FRT sites, and catalyzes recombination ... WebCatalog number: K601001.
