Our satisfied customers say...

"The scientists at Dualsystems were helpful collaborators, very responsive to our requests, and screened additional libraries as needed to provide us with compelling data. The final results included several confirmed interacting proteins for our targets of interest and we were very satisfied with the yeast 2-hybrid service"
