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.

摘要:An object of the present invention is to provide a method of treatment and a method of storage that are useful in conducting a nucleic acid synthesis procedure capable of directly amplifying an intended nucleic acid in a living body-derived sample without purification steps.The present invention provides a method for synthesis of nucleic acids in which a living body-derived sample itself is mixed with a reaction solution for gene amplification and allowed to react, which method comprises treating the sample with a surfactant before the reaction to destruct solid components such as cells or bacterial bodies containing nucleic acids and uniformly disperse them in the sample liquid.
