Consortium Plasmids Insect Cell Vectors Luciferase Vectors pcDNA5/FRT The yeast FLP system has been studied intensively (7, 8, 22, 36). The only requirements for FLP recombination are the FLP protein and the FLP recombination target (FRT) sites on the DNA substrates. The minimal functional FRT site contains only 34 bp. The FLP protein can promote both inter- and intramolecular recombination To overcome the limited availability of antibiotic resistance markers in filamentous fungi, we adapted the FLP/FRT recombination system from the yeast Saccharomyces cerevisiae for marker recycling. We tested this system in the penicillin producer Penicillium chrysogenum using different experimental approaches. In a two-step application, we first integrated ectopically a nourseothricin.

Here, we tested the FLP/FRT recombination system in a construct containing a two gene cassette organization and examined its potential in transgenic Arabidopsis and tobacco plants using a b-glucuronidase (GUS) reporter.

Since the Flp/FRT system appears to be free of toxic side effects, as recently reported for the Cre/lox counterpart, Flp-RMCE continues to gain relevance (see Supplementary Data). Major upcoming applications for RMCE rely on several sets of recombinase target site 以前はX線などを用いたが、現在では組換え酵素flippase(FLP)とその標的配列(flippase recognition target、FRT)を利用して体細胞組換えを誘発することでクローンを作成するのが一般的である [2] [10] The Flp-FRT system and Cre-loxP induce gene recombination in a similar way. The obvious difference between the two systems is that the recombinase (Cre and Flp) has different optimal reaction temperatures. Studies have found that Cre recombinase is the best The temperature is 37 oC and Flp recombinase is 30℃. Dre-Rox system DNA recombinase Flp can be developed into promising alternatives. We demonstrate that the Flp variant evolved to recombine an FRT-like sequence, FL-IL10A, which is located upstream of the human interleukin-10 gene, and ca

Abstract. The FLP enzyme catalyzes recombination between specific target sequences in DNA. Here we use FLP to temporally and spatially control gene expression in the nematode C. elegans. Transcription is blocked by the presence of an off cassette between the promoter and the coding region of the desired product Because Cre and Flp recombine distinct DNA target sites, loxP and FRT, respectively (Branda and Dymecki, 2004), these two highly efficient site-specific recombinase systems (Cre-loxP and Flp-FRT) have been used to create genetically engineered mice with a targeting construct with a removable positive selection cassette (Meyers et al., 1998) FLP-FRT recombination.
