We asked Hybrigenics to select intrabodies against four different proteins involved in vesicular trafficking. They quickly provided us with several candidates per protein, in the form of ready-to-use plasmids for mammalian expression. We already validated some of these intrabodies. Fused to a red fluorescent protein, they will be extremely valuable tools to block our target proteins in live cells — Dr. Thierry Galli (Jacques Monod Institute, Paris, France) - Europe
