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 flippase (Flp) derived from the 2 µ plasmid of baker's yeast Saccha… WebApr 1, 1998 · Recently, the use of the FLP/FRT system has allowed for the high-frequency production of mosaic animals for 95% of Drosophila genes.
