摘要： Compositions, preparations, systems, and related methods for delivering a supercharged protein, or a complex of a supercharged protein and an agent (e.g., nucleic acids, peptides, proteins, small molecules) to cells are provided. Such systems and methods include the use of supercharged proteins. For example, superpositively charged proteins may be associated with nucleic acids (which typically have a net negative charge) via electrostatic interactions. In some embodiments, such systems and methods involve altering the primary sequence of a protein in order to "supercharge" the protein (e.g., to generate a superpositively-charged protein). In some embodiments, complexes comprising supercharged proteins and one or more agents to be delivered are useful as therapeutic agents. In some embodiments, complexes and/or pharmaceutical compositions thereof are administered to a subject in need thereof. The inventive complexes or pharmaceutical compositions thereof may be used to treat proliferative diseases, infectious diseases, cardiovascular diseases, inborn errors in metabolism, genetic diseases, etc.
