Cat. No. Description Pcs./Box
60260 Fuse-It-T, red fluorescent: ready to use, 3 mM, 100 µl 1
60261 Fuse-It-T, red fluorescent: ready to use, 3 mM, 400 µl 1


  • Live cell imaging in a tissue environment for any kind of microscopic technique, including those optimized for thick specimens (e.g., confocal, two-photon, and light-sheet microscopy)
  • Labeling of tissue samples before microtome dissection

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.

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.
