  • Method for delivery of nucleic acids to cells using hypericin polyamine complexes
    Patent number: 5824654
    Abstract: The invention provides improved methods for delivery of nucleic acids to cells, which comprise forming ternary complexes between a hydrophobic, membrane-binding anion such as hypericin; a polycation such as polylysine; and a nucleic acid such as DNA; and contacting cells with the tenary complexes. Also provided are pharmaceutical formulations comprising these ternary complexes and a pharmaceutically acceptable carrier or diluent. The methods and compositions find use in mediating DNA uptake into cells, including gene therapy applications.
