---|---|
US8058069B2 CLAIM 1 . A nucleic acid-lipid particle comprising : (a) a nucleic acid (nucleic acid) ; (b) a cationic lipid (cationic lipid) comprising from 50 mol % to 65 mol % of the total lipid present in the particle ; (c) a non-cationic lipid comprising a mixture of a phospholipid and cholesterol or a derivative thereof , wherein the phospholipid comprises from 4 mol % to 10 mol % of the total lipid present in the particle and the cholesterol or derivative thereof comprises from 30 mol % to 40 mol % of the total lipid present in the particle ; and (d) a conjugated lipid that inhibits aggregation of particles comprising from 0 . 5 mol % to 2 mol % of the total lipid present in the particle . |
GENE-TRANSFER OPTIMIZATION WITH LIPOSPERMINE-COATED DNA . Designed synthetic DNA carriers represent an attractive alternative to the widely used calcium phosphate gene transfer technique . In this context , we developed a class of nucleic acid (nucleic acid) binding lipids , the lipopolyamines , which spontaneously condense DNA on a cationic lipid (cationic lipid) layer . The resulting nucleolipidic particles transfect most animal cells efficiently . However , compaction depends on many experimental factors , some of which have been varied here to give optimal transfection efficiency . When plasmid condensation by the lipospermine is performed in the absence of competing polyions or serum proteins , or when the gene of interest is diluted into carrier DNA , transfection efficiency is increased by 2-3 orders of magnitude . With these improvements , chloramphenicol acetyl transferase activity resulting from transfection of as little as 25 ng could easily be detected by a nonradioactive ELISA test . |
US8058069B2 CLAIM 2 . The nucleic acid-lipid particle of claim 1 , wherein the nucleic acid (nucleic acid) comprises a small interfering RNA (siRNA) . |

GENE-TRANSFER OPTIMIZATION WITH LIPOSPERMINE-COATED DNA . Designed synthetic DNA carriers represent an attractive alternative to the widely used calcium phosphate gene transfer technique . In this context , we developed a class of nucleic acid binding lipids , the lipopolyamines , which spontaneously condense DNA on a cationic lipid (cationic lipid) layer . The resulting nucleolipidic particles transfect most animal cells efficiently . However , compaction depends on many experimental factors , some of which have been varied here to give optimal transfection efficiency . When plasmid condensation by the lipospermine is performed in the absence of competing polyions or serum proteins , or when the gene of interest is diluted into carrier DNA , transfection efficiency is increased by 2-3 orders of magnitude .

US8058069B2 CLAIM 1 . A nucleic acid-lipid particle comprising : (a) a nucleic acid (stranded nucleic acid) ; (b) a cationic lipid comprising from 50 mol % to 65 mol % of the total lipid present in the particle ; (c) a non-cationic lipid comprising a mixture of a phospholipid and cholesterol or a derivative thereof , wherein the phospholipid comprises from 4 mol % to 10 mol % of the total lipid present in the particle and the cholesterol or derivative thereof comprises from 30 mol % to 40 mol % of the total lipid present in the particle ; and (d) a conjugated lipid that inhibits aggregation of particles comprising from 0 . 5 mol % to 2 mol % of the total lipid present in the particle . |
CHEMICALLY MODIFIED OLIGONUCLEOTIDES AS PROBES AND INHIBITORS . Oligonucleotides bind specifically to single-stranded nucleic acid (nucleic acid, nucleic acid mass ratio) s to form a double helix if there is a complementary antiparallel nucleotide sequence . In addition , certain oligonucleotides bind specifically to a variety of proteins . Therefore , biological processes involving these nucleic acids or proteins can be modulated (normally inhibited) by addition of the respective oligonucleotides . The effects of these oligonucleotides and the fields of potential application can be broadened by the introduction of chemically modified nucleotides . For instance , replacing oligonucleotide phosphate groups by methylphosphonates results in the loss of one negative charge per nucleotide and the oligonucleotide becomes more lipophilic . An oligonucleotide carrying a reactive group can modify its binding partner . An oligonucleotide covalently linked to a dye can be localized in a biological specimen . Oligonucleotides attached to an enzyme can be detected in very small amounts since the enzyme can catalyze the formation of large amounts of the substance assayed (e . g . , a fluorescent product) . An important biochemical application is the detection and localization of a messenger RNA or its gene . Medical applications include the detection of bacterial or viral sequences . There is also great interest in inhibiting the translation of messenger RNA and the transcription and replication of DNA . So-called antisense oligonucleotides are currently being used for the inhibition of protein biosynthesis and of reverse transcription of retroviruses . |

A NEW CATIONIC LIPOSOME REAGENT MEDIATING NEARLY QUANTITATIVE TRANSFECTION OF ANIMAL-CELLS .
