    • Disclosed are compositions for isolating populations of nucleic acids from biological, forensic, and environmental samples. Also disclosed are methods for using these compositions as one-step formulations for killing pathogens, inactivating nucleases, and releasing polynucleotides from other cellular components within the sample, and stabilizing the nucleic acids prior to further processing or assay. The disclosed compositions safely facilitate rapid sample collection, and provide extended storage and transport of the samples at ambient or elevated temperature without contamination of the sample or degradation of the nucleic acids contained therein. This process particularly facilitates the collection of specimens from remote locations, and under conditions previously considered hostile for preserving the integrity of nucleic acids released from lysed biological samples without the need of refrigeration or freezing prior to molecular analysis.
    • 公开了用于从生物,法医和环境样品中分离核酸群体的组合物。 还公开了将这些组合物用作用于杀死病原体,灭活核酸酶以及从样品中的其他细胞组分释放多核苷酸的一步制剂,以及在进一步加工或测定之前使核酸稳定的方法。 所公开的组合物安全地促进快速样品收集,并且在环境温度或升高的温度下提供样品的延长的储存和运输,而不会污染样品或其中所含的核酸的降解。 该方法特别有助于从远程位置收集标本,并且在先前被认为是敌对的条件下收集样品,以保持从裂解的生物样品中释放的核酸的完整性,而不需要在分子分析之前进行冷冻或冷冻。
