A fusion reagent used to transfer water soluble proteins into the cytoplasm of living cells
- The lumen of fusogenic liposomes is used as a carrier for water soluble proteins
- Superior fusion efficiency (up to 80-100%)
- Fusion process completed within 1 - 20 minutes
- Optimized for the transfer of low and intermediate protein amounts to prevent concentration-induced artifacts in cell behavior

The incorporation of small liposomal carriers into the plasma membrane of mammalian cells is the idea behind all of ibidi’s Fuse-It products. Liposomal carriers are able to attach and instantly fuse with plasma membranes in a physicochemical-driven manner. ibidi’s new Fuse-It reagents efficiently use this mechanism and fuse with mammalian cell surfaces immediately upon contact. Therefore, this novel technique makes the transfer of molecules independent of biological processes, such as endocytosis, pinocytosis, or specific receptor binding.

“For my group, the efficient labeling of cells is an extremely important issue. Since most of our cells are very sensitive to changing medium conditions, mild and fast labeling is a must. We have found, in the very short time we have used the system and therefore without real optimization, that both the Fuse-It-Color and Fuse-It-P were very well functional, with the latter perfectly capable of delivering our target proteins into HeLa cells. Such delivery was obtained using relatively low amounts of exogenous proteins and incubation times as short as 5 minutes.”

"The incorporation of transmembrane proteins from proteoliposomes or detergent-containing buffers into black lipid membranes is a very dicey issue. I have used your high fusogenic Fuse-It-P for this purpose and it really worked perfectly. It was an extremely simple preparation, and the incorporation was very reliable and easily adjustable. It made this very difficult step for all experiments in my institute much easier. Thanks a lot."
