Abstract:
1. A delivery system for introducing a cargo molecule into cytosol of a living cell, the system comprising: a first membrane binding element linked to an endosomal compartment disrupting element through a first linker having one or more anionic moieties; and a second membrane binding element linked to an exogenous cargo molecule through a second linker having one or more anionic moieties, the second linker having a region that is selectively cleavable, wherein the first and second membrane binding elements both induce endocytosis into an early/recycling endosome and the endosomal compartment disrupting element destabilizes the early/recycling endosome such that the exogenous cargo molecule is released from the second membrane binding element and into the cytosol of the living cell.
