PCR inhibition is the most common cause of amplification failure when sufficient copies of DNA are present. PCR inhibitors usually affect PCR through interaction with DNA or interference with the DNA polymerase. Inhibitors can escape removal during the DNA purification procedure by binding directly to single or double-stranded DNA. Alternatively, by reducing the availability of cofactors (such as Mg2+) or otherwise interfering with their interaction with the DNA polymerase, PCR is inhibited.〔 In a multiplex PCR reaction, it is possible for the different sequences to suffer from different inhibition effects to different extents, leading to disparity in their relative amplifications.〔 ==Types of inhibitors== Inhibitors may be present in the original sample, such as blood, fabrics, tissues and soil but may also be added as a result of the sample processing and DNA extraction techniques used.〔 Excess salts including KCl and NaCl, ionic detergents such as sodium deocycholate, sarkosyl and SDS, ethanol, isopropanol and phenol among others, all contribute via various inhibitory mechanisms, to the reduction of PCR efficiency.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polymerase chain reaction inhibitors」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
