在本报告中,我们推出了 DNAzol(R),这是一种正在申请专利的 DNA 分离试剂,含有硫氰酸胍和洗涤剂混合物。它是一种完整、无毒、即用型试剂,用于从各种生物来源中分离基因组 DNA。在 DNAzol 方案中,生物样品在 DNAzol 中匀浆(或裂解),然后用乙醇沉淀 DNA,洗涤并溶解在 8 mM NaOH 中。 pH 调整后,DNA 可立即用于分析或保存在 4°C 下。整个分离可在 20-30 分钟内完成,并且可分离多种 DNA 分子,包括长度低至 0.1 kb 的基因组 DNA mid DNA 片段。如有必要,样品可以在室温下在 DNAzol 中保存较长时间。分离的 DNA 可用于 PCR、Southern blotting 和其他分子生物学应用,无需任何额外纯化。
In this report, we present DNAzol(R), a patent-pending DNA isolation reagent containing guanidine thiocyanate and a detergent mixture. It is a complete, nontoxic and ready-to-use reagent for the isolation of genomic DNA from various biological sources. In the DNAzol protocol, a biological sample is homogenized (or lysed) in DNAzol, and the DNA is precipitated with ethanol, washed and dissolved in 8 mM NaOH. Following pH adjustment, the DNA can be used immediately for analysis or stored at 4 degrees C. The entire isolation can be completed in 20-30 min, and a wide range of DNA molecules can be isolated including genomic DNA mid DNA fragments down to 0.1 kb in length. If necessary, samples can be stored in DNAzol at room temperature for extended periods of time. The isolated DNA is ready for PCR, Southern blotting and other molecular biology applications without any additional purification.
