SummaryEfficient intracellular delivery of biomolecules is important for many different biological and biotechnological applications in living organisms, and is a prerequisite for certain types of fundamental and applied research. One major challenge is the delivery of unmodified, functional cargoes in a simple, time-efficient, and high-throughput manner. Herein, we present an efficient strategy that uses fusion peptides containing cell penetrating peptide, endosomal escape domain, and a sarcosine linker to introduce biomolecules, namely fluorescent protein and dextran, via macropinocytosis into the cells of various land plants and microalgae. Our peptide-mediated delivery system allows for high-throughput delivery of functional biomolecules within a few minutes to a few hours as well as open new possibilities for biology and biotechnology using difficult-to-transfect cell types. |
