  • Formulations and methods for generating active cytofectin: polynucleotide transfection complexes
    Patent number: 5925623
    Abstract: In the generation of cytofectin:polynucleotide complexes for transfection of cells, formulations, counterions, and reaction conditions for maximizing the transfection include using a cationic amine compound that has the general structure: ##STR1## wherein R.sub.4 and R.sub.5 are a pair of same or different lipoyl moieties selected from a group consisting of an alkyl, alkenyl, alkynyl, alkanoyl, alkenoyl, or alkynoyl groups and for R.sub.1, R.sub.2, and R.sub.3 at least two are hydroxylated, ether containing, or acyloxy containing alkyl, alkenyl, or alkynyl groups or at least one amine bonded halogen containing moiety selected from a group consisting of a halogenated alkyl, alkenyl, or alkynyl group or a mixture of at least one halogen containing moiety selected from a group consisting of a halogenated alkyl, alkenyl, or alkynyl group and at least one hydroxylated, ether containing, or acyloxy containing alkyl, alkenyl, or alkynyl group, and X.sup.- is an oxyanion or halide counterion.
    Type: Grant
