What is RMCE?
RMCE stands for Recombinase-mediated Cassette Exchange, a method used for targeted gene editing.
How long does it take to generate RMCE lines?
The RMCE lines can be generated in approximately 15 days.
What are the advantages of using hPSCs?
hPSCs are pluripotent and can differentiate into various cell types, making them valuable for research.
Can this method be applied to other loci?
Yes, while the focus is on the AAVS1 locus, the method can be adapted for other human permissive loci.
What is the significance of isogenic lines?
Isogenic lines are genetically identical except for the targeted modification, allowing for accurate comparative studies.
What role does flippase play in this method?
Flippase is used to facilitate the exchange of genetic cassettes at the target locus during RMCE.
