WebMar 1, 1999 · Mosaic analysis has been widely used in Drosophila for studying the functions of known genes, while the more recent introduction of the high efficiency FLP/FRT system (Golic and Lindquist 1989), together with means to effectively mark clones (Xu and Rubin 1993), has allowed the use of mosaic systems to screen for new mutants.

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 ... 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. Cell markers have been …
Webhave developed a system for generating mosaic clones by combining Gal4/UAS and flippase (FLP)/FRT system which will allow generation of loss-of-function as well as gain-of-function clones on the dorsal and ventral eye margins. We used the bifid-Gal4 driver to drive expres-sion of UAS-FLP. This reagent can have multiple appli- Websuggest that either the frequency of FLP/FRT mediated mitotic recombination is much lower than that of intra-chromosomal flip-out, or that most of the lines that score positive for flip-out assay but negative for trans-FRT assay start their expression in post-mitotic neurons, or both.

WebJun 9, 2024 · Mosaic analysis using the FLP/FRT system allows investigating the roles of essential genes during wing development in Drosophila melanogaster. This chapter describes the practical methods to isolate Notch signaling regulators by somatic mosaic screen. The fly stocks, cross schemes, and screen parameters are summarized. WebNov 6, 2024 · The FLP-FRT system is similar to the Cre-lox system and is becoming more frequently used in mouse-based research. It involves using flippase (FLP) recombinase, …
Webtissues, the FRT/FLP system has been shown to be func-tional in both male and female germ-line cells (Golic, 1991; Chou and Perrimon, 1992). The use of the FRT sequence to induce high frequency mosaicism for a particular gene requires that the FRT sequence be located closer to the cen - tromere than the gene of interest. We have introduced dom -
WebThe Gal4-UAS system has been combined successfully with the FLP-FRT technology to develop novel ways to create mosaics.
