专利号:US-10501782-B1 优先权日:2014-09-05 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.
专利号:US-3846399-A 优先权日:1969-04-10 标题:Process for controlled stepwise synthesis of polypeptides 发明人:HIRSCHMANN R; DENKEWALTER R 权利人:MERCK & CO INC 摘要:The invention disclosed herein relates to a novel process for the controlled, stepwise synthesis of polypeptides and proteins. More particularly, it is concerned with a process for the rapid and efficient preparation of polypeptides in which multiple sequential steps are carried out without isolation of intermediate peptides. This process for the controlled stepwise synthesis of polypeptides involves reacting a starting amino acid or peptide (or derivative thereof) with an N-carboxy amino acid anhydride (or derivative thereof) in an aqueous medium under conditions of controlled pH such that the only amino group present in appreciable concentration in reactive form during the course of the reaction is the amino group in the starting amino acid or peptide.
专利号:US-10801022-B2 优先权日:2015-04-14 标 题:Method for solid-phase synthesis of DNA encoded compound library 发明人:LI JIN; Wan jinqiao; LIU GUANSAI; DOU DENGFENG 权利人:HITGEN LTD; HITGEN INC 摘要:The present invention provides a method of solid-phase synthesis of DNA-encoded compound library. The method includes following steps: a) reacting solid carrier G-1 with linker molecule L-1 to prepare L-G-1; b) reacting DNA with linker molecule L-0 to prepare L-2; c) reacting L-G-1 with L-2 to prepare L-G-2; d) removing protection group of the L-G-2 and obtaining L-G-2-1; e) reacting the L-G-2-1 with synthetic building block and performing DNA encoding; and f) removing the solid carrier and obtaining the DNA-encoded compound library. Compared with the prior art, the present invention can complete post-treatment purification of the reaction only by filtration and irrigation processes for several times. The present invention is simple to operate, can shorten the production cycle of DNA encoded compound library with more than 50%, significantly increases the production efficiency and the unicity as well as the purity of the final products.

专利号:US-7399610-B2 优先权日:2004-10-15 标 题:Method for cell-free protein synthesis using extract solution derived from insect cell 发明人:SHIKATA MASAMITSU; HANAFUSA NOBUHIRO; KOBAYASHI SHINICHIRO 权利人:SHIMADZU CORP 摘要:The present invention provides a simple cell-free protein synthesis method capable of affording synthesis of a protein in a high amount in a short time at a low cost. A method for cell-free protein synthesis using an extract derived from an insect cell, the method comprising removing a component which can pass through a semipermeable membrane through the semipermeable membrane while maintaining synthesis reaction, thereby to continuously synthesize a protein. Preferably, an mRNA is additionally supplied while said synthesis reaction is maintained. Further, said insect cell is preferably an established culture cell derived from Trichoplusia ni ovum cell.
专利号:US-2025136636-A1 优先权日:2021-08-16 标 题:Nucleotide complexes capable of an improved dna synthesis yield 发明人:KYSH DANIEL; ROTHWELL PAUL 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.
