TīmeklisThe Cre/lox system is a well-established research tool, especially in the field of mouse transgenics. A few of the most common uses are listed below. Cre-dependent gene expression – placing a stop codon with loxP sites on either side (often called a “lox-stop-lox” or “LSL” cassette) upstream of a gene of interest will prevent gene ... TīmeklisThe Cre-lox system, derived from P1 bacteriophage, is a potent and specific system for controlling gene expression. The protein Cre recombinase recognizes 34 bp loxP sites, and the orientation and location of the loxP sites determines how the genetic material will be rearranged. The schematic below shows the three types of rearrangements ...

TīmeklisRecombinase polymerase amplification (RPA) is a single tube, isothermal alternative to the polymerase chain reaction (PCR). [1] By adding a reverse transcriptase enzyme to an RPA reaction it can detect RNA as well as DNA, without the need for a separate step to produce cDNA ,. [2] [3] [4] Because it is isothermal, RPA can use much simpler ...
