split ubiquitin system

Does anyone have experience with any of the versions of the split ubiquitin yeast two hybrid system to investigate potential protein-protein interactions? My lab is interested in using this system, but it’s been difficult to track down the original source of the plasmids. Also, we’re wondering if anyone can comment on the reliability of the split ubiquitin systems and/or provide suggestions regarding methodology. Many thanks for your help!


don’t know how much this goes towards answering all your specific questions, but these guys have published recently on using the split system in worms and they describe the source of their plasmids.


They can perhaps say something on reliability/protocols etc?
