Membrane fusion is a novel and highly superior method to incorporate various molecules and particles into mammalian cells, and a strong strategy for functional studies and therapeutic approaches.
The incorporation of small liposomal carriers into the plasma membrane of mammalian cells is the idea behind all of ibidi’s Fuse-It products. ibidi offers specifically optimized products based on the molecular classes required for your research.
Specific 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.
Membrane fusion makes it possible to effectively incorporate different classes of molecules into the cellular membrane or into the cytoplasm. Systematic adaptations of the liposome composition to the general characteristics of a defined molecular class guarantee fusion efficiencies up to 80 - 100% within only seconds to a few minutes. Additionally, the very short incubation times provide an almost unaffected cell behavior after the molecule transfer.
