  The present invention provides a method for extracting a nucleic acid from a sample and depleting inhibitors contained in the sample, comprising: a) preparing an extraction mixture by contacting the sample with i) at least one cationic detergent capable of forming a precipitate with inhibitors contained in the sample, ii) at least one salt, wherein the salt is contained in the extraction mixture in a concentration to prevent precipitation of the nucleic acid in the presence of the cationic detergent, and iii) at least one water-insoluble non-ionic polymeric adsorbent; b) incubating the extraction mixture and forming a precipitate which comprises the cationic detergent and inhibitors contained in the sample and separating the formed precipitate from the supernatant, thereby providing an inhibitor depleted supernatant which comprises the extracted nucleic acid. Also provided is a kit for performing said method.

  本发明提供了一种从样品中提取核酸并消耗样品中所含抑制剂的方法，包括 a) 将样品与以下物质接触，制备提取混合物 i) 至少一种能与样品中所含抑制剂形成沉淀的阳离子洗涤剂、 至少一种盐，其中盐在提取混合物中的浓度可防止核酸在阳离子洗涤剂存在下沉 淀，以及 iii) 至少一种不溶于水的非离子聚合物吸附剂； b) 培养提取混合物，形成包含阳离子洗涤剂和样品中所含抑制剂的沉淀，并将形成的沉淀与上清液分离，从而提供包含提取核酸的去抑制剂上清液。 此外，还提供了用于执行上述方法的试剂盒。
