FLP-FRT recombination

In genetics, Flp-FRT recombination is a site-directed recombination technology, increasingly used to manipulate an organism's DNA under controlled conditions in vivo. It is analogous to Cre-lox recombination but involves the recombination of sequences between short flippase recognition target (FRT) sites by the recombinase(Flp)derived from the 2 µm plasmid of baker's yeast Saccharomyces cerevisiae.
