WebKey words FLP/FRT, Drosophila melanogaster, Wing, Notch signaling 1 Introduction Creating mosaic animals enables investigating the roles of essential genes in speciﬁc developmental events such as cell fate determina-tion, tissue growth, and pattern formation [1]. The FLP/FRT system remains the premier tool for generating mosaic tissues in WebThe efficacy of this system was examined using the FRT site-flanked genes HSP104, URA3 and GFP. The pre-excision frequency of this system, which might be caused by the basal activity of the GAL1 promoter or by spontaneous recombination between FRT sites, was detected ca. 2% under the non-selecting condition.

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… WebJan 1, 1994 · The position of the FRT sites in our stocks mean that the approximately 34.
