The presence of polymerase-chain-reaction (PCR) inhibitors in many environmental samples can make reliable and repeatable quantitative-polymerase-chain-reaction (qPCR) analysis difficult without sample dilution. To estimate an optimal sample dilution for qPCR and reduce effects of inhibition, a simple test based on multiple dilution series of samples is presented that avoids the use of internal controls and standards reducing complexity and cost.
许多环境样本中存在聚合酶链反应（PCR）抑制剂，如果不进行样品稀释，就很难进行可靠和可重复的定量聚合酶链反应（qPCR）分析。为了估计 qPCR 的最佳样品稀释度并减少抑制作用的影响，提出了一种基于多个样品稀释系列的简单测试方法，该方法避免了使用内部对照和标准品，从而降低了复杂性和成本。
