专利号:US-2023220434-A1 优先权日:2020-01-09 标 题 :Composistions and methods for crispr enabled dna synthesis 发明人:LYNCH MICHAEL DAVID; MOREB EIRIK ADIM; YANG TIAN 权利人:UNIV DUKE 摘要:Methods for CRISPR Enabled DNA Synthesis and compositions arising from the methods are provided. The methods may include ligation of partially single stranded DNA donor and acceptor oligonucleotides that are covalently linked to a subsequence of the target DNA to be sequenced followed by cleavage of the ligated product. In this manner the donor and acceptor oligonucleotides shuttle a growing subsequence of the target DNA with each cycle. A mutant Cpfl nuclease is missing non-specific ssDNA nuclease activity may be used for cleavage of the ligation product. Fourteen ligation/cleavage cycles can result in synthesis of ssDNA of greater than 10,000 bp in length.

Methods for purification of synthetic oligonucleotides are also provided. Instrumentation configurations for oligonucleotide synthesis are also provided. Methods of designing and synthesizing polynucleotides are also provided. Polynucleotide design is optimized for subsequent assembly from shorter oligonucleotides. Modifications of phosphoramidite chemistry to improve the subsequent assembly of polynucleotides are provided. The design process also incorporates codon biases into polynucleotides that favor expression in defined hosts. Design and assembly methods are also provided for the efficient synthesis of sets of polynucleotide variants. Software to automate the design and assembly process is also provided.
专利号:US-7105666-B2 优先权日:2002-06-27 标 题:Synthesis of purine derivatives 发明人:HAMMARSTROEM LARS G J; KRAUSS NANCY ELISABTH; LABADIE SHARADA SHENVI; SMITH DAVID BERNARD; TALAMAS FRANCISCO XAVIER 权利人:ROCHE PALO ALTO LLC 摘要:The present invention provides a method for producing 2-, 6-, 8- and 9-substituted purine compounds from 4,6-dihalo-5-nitro-2-alkyl-pyrimidine compounds in solution or by solid phase techniques. The present process provides for the sequential introduction of amine substituents at the 4- and 6-positions, displacement of an alkylsulfony group at the 2-position of the pyrimidine, reduction of the nitro group and formation of the imidazole portion of the purine compound. Furthermore, the methods of the present invention are ideally suited to the preparation of a library of purine compounds.

专利号:US-6232462-B1 优先权日:1994-08-30 标题:Reduction of nonspecific hybridization by using novel base-pairing schemes 发明人:COLLINS MARK L; HORN THOMAS; SHERIDAN PATRICK J; WARNER BRIAN D; URDEA MICHAEL S 权利人:BAYER AG 摘要:Methods are provided for substantially reducing background signals encountered in nucleic acid hybridization assays. The method is premised on the elimination or significant reduction of the phenomenon of nonspecific hybridization, so as to provide a detectable signal which is produced only in the presence the target polynucleotide of interest. In addition, a novel method for the chemical synthesis of isoguanosine or 2′-deoxy-isoguanosine is provided. The invention also has applications in antisense and aptamer therapeutics and drug discovery.
