标题:Cell-free synthesis of DNA by strand displacement
发明人：PORTER NEIL; ROTHWELL PAUL; EXTANCE JONATHAN
权利人:TOUCHLIGHT IP LTD
摘要:The present invention relates to an improved process for synthesis of DNA, RNA, proteins and like molecules, in particular cell-free enzymatic synthesis of DNA, preferably in large scale. The present invention relates to the synthesis of DNA using strand-displacement replication and the addition of nucleotides to the reaction mixture is controlled, thus controlling yield. The reaction mixture contains a starting amount of nucleotides, polymerase and DNA template, to which further nucleotides are supplied in a controlled manner.

权利人:HARVARD COLLEGE
摘要:Methods and apparatus of modulating polynucleotide synthesis are provided. The methods include delivering reagents comprising enzymes, nucleotides and ions to oligonucleotide primers wherein the reagents catalyze incorporation of the nucleotides to 3′ ends of the oligonucleotide primers, and modulating incorporation of the nucleotides to the 3′ ends of the oligonucleotide primers. Polynucleotide synthesis is modulated by modulating presence or absence of catalytic cation cofactors to provide sequence defined synthesis of polynucleotides. In certain embodiments, the polynucleotides encode information.

权利人:TOUCHLIGHT IP LTD
摘要:The present invention relates to novel nucleotide complexes which enhance the enzymatic production of DNA. The nucleotide complexes includes a divalent cation at a ratio of 0.2-1.5 divalent cations per nucleotide, whilst monovalent ions (other than hydrogen or hydronium ions from any solvent) are minimal. The nucleotide complexes have desirable properties for the synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large or industrial scale. Further, the invention includes improved processes for preparing said nucleotide complexes. Further complexes are disclosed which possess unique properties in accelerating DNA synthesis at higher concentrations, these complexes also containing zwitterion molecules.

权利人:TOUCHLIGHT IP LTD
摘要:The present invention relates to an improved process for synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large or industrial scale, with an improved yield and/or with an improved efficiency. The invention requires the use of nucleotide complexes wherein the nucleotide is associated with a mixture of divalent and monovalent cations. Preferably, the divalent cation may be magnesium or manganese.
