After membrane fusion, cells can immediately be analyzed. Accurate characterization of cell number, localization, and intercellular crosstalk is vital for an overall understanding of cell behavior in tissues. For the very first time, Fuse-It-T enables you to do all of these processes in just one single step. Upon request, additional labeling can be provided.

Principle of Membrane Fusion

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.
