  Nucleic acids can be made available for amplification or other treatment after admixture of a sample with specific weakly basic polymers to form a precipitate with the nucleic acids at acidic pH. After removing non-precipitated materials, the pH is then made basic, thereby releasing the nucleic acids from the polymer. This method for preparing specimen samples is simple and quite rapid, and the released nucleic acids can be further treated in hybridization assays or amplification procedures. No surfactant or other cell lysing reagents are employed. The weakly basic polymers are water-soluble and cationic at acidic pH, but neutral in charge at basic pH.

  核酸可以在样本与特定弱碱性聚合物混合后，在酸性pH下形成与核酸共沉淀后，用于扩增或其他处理。去除非沉淀物质后，将pH调为碱性，从而释放核酸与聚合物。这种制备标本样品的方法简单且非常快速，释放的核酸可以进一步用于杂交分析或扩增程序中。不使用表面活性剂或其他细胞裂解试剂。这些弱碱性聚合物在酸性pH下是水溶性和阳离子性的，但在碱性pH下是中性的。
