专利号:US-12195777-B2 优先权日:2018-02-02 标 题 :Polynucleotide synthesis method, kit and system 发明人:HERON ANDREW JOHN 权利人:OXFORD NANEPORE TECH PLC; OXFORD NANOPORE TECH PLC 摘要:The invention relates to new in vitro methods for synthesising a polymer, particularly a polynucleotide molecule, having a pre-defined sequence of units such as nucleotides. For synthesising a polynucleotide molecule the methods involve a process of extending a polynucleotide synthesis molecule with a transfer nucleotide. The methods additionally involve repeating the extension process multiple times to iteratively extend the polynucleotide molecule with multiple transfer nucleotides to generate a new polynucleotide molecule having a pre-defined nucleotide sequence. The invention also relates to in vitro methods of joining multiple synthetic polynucleotides following synthesis to form larger synthetic polynucleotides, as well as devices and systems for performing the extension, synthesis and assembly methods of the invention.

专利号:US-2007264694-A1 优先权日:2006-04-07 标题 :Use of non-standard bases and proximity effects for gene assembly and conversion of non-standard bases to standard bases during dna synthesis 发明人:PRUDENT JAMES R 权利人:ERAGEN BIOSCIENCES INC 摘要:The present methods relate to generating nucleic acid molecules using non-natural nucleotides. In some methods, the nucleic acid molecules may be generated by hybridizing a plurality of oligonucleotides comprising one or more non-natural nucleotides and using a polymerase and/or a coupling agent to link the hybridized oligonucleotides. The methods also relate to the use of proximity effects to generate nucleic acid molecules using non-natural nucleotides. Furthermore, the methods relate to the use of at least one non-natural base in a DNA template in order to generate a replicate of the DNA template in which the non-natural base has been replaced with a natural base.

For example, provided are compositions that include DNA oligonucleotides that have targeting specificity for RNA encoding mutant huntingtin protein. When introduced into a cell, the DNA oligonucleotides reduce expression of the mutant huntingtin protein in a cell. For example, the DNA oligonucleotide, functioning as an enzymatic DNA molecule (or DNAzyme), cleaves the RNA encoding the mutant mRNA protein, thereby rendering the mRNA incapable of expression. That is, the cleavage event renders the RNA non¬ functional and reduces or abrogates protein expression from that RNA. Hence, synthesis of the mutant huntingtin protein is selectively reduced or inhibited, in accordance with the methods and compositions described herein. By silencing or reducing the expression of the mutant huntingtin protein, the methods and compositions describe herein can be used to treat Huntington's disease, including adult and juvenile onset Huntington's disease.
