| 目的：建立一种经济、快速且高质量提取人体外周凝血DNA 的方法。方法：摸索最佳的匀浆条件，对外周凝血块进行匀浆，
采用KI 法对匀浆液进行基因组DNA 的提取，通过凝胶电泳、单重PCR 和多重PCR 检测凝血基因组DNA 的提取产量和质量，
并分别与常规的凝血基因组DNA 提取方法，即蛋白酶K 消化法，以及提取抗凝血基因组DNA 的KI 法进行比较分析。结果：最
佳的匀浆条件为：39000 rmp，15 秒。在此条件下提取的基因组DNA 完整性好，纯度和产量与蛋白酶K 消化法提取凝血DNA 和
KI 法提取抗凝血DNA 的结果相比，没有统计学差异。单重PCR 和多重PCR 也获得了理想的扩增结果。结论：与常规的外周凝血
提取方法相比（蛋白酶K 消化法），本方法节省了时间和成本，能快速、经济、有效地提取外周凝血基因组DNA，可用于后续的科
研和临床诊断需要，解决了部分科研机构血液基因组DNA 的样本来源问题。 |

| Objective: To establish a rapid, economical method for extracting genomic DNA from peripheral clotted blood.
Methods: Explore a optimum homogenate condition, homogenate the clotted blood, extracting the genomic DNA by KI method. Use
agarose gel electrophoresis, single PCR and multiplex PCR detect the genomic DNA extraction yield and quality. And compared with the
traditional extraction methods, Proteinase K digestion method and KI method which extract DNA from anti-coagulated blood. Results:
The optimum homogenate condition is 39000 rmp and 15 seconds. The genomic DNA was extracted under this condition has good
integrity. There is no significant difference of purity and yield between this method and Proteinase K digestion and KI method. Single
PCR and multiplex PCR also obtained good amplification results. Conclusion: Compared with traditional extraction methods (Proteinase
K digestion method),this method can save time and cost,which can extract DNA rapidly,economical and effectively,and can be used in
clinical and research analysis, and can solve the blood genomic DNA sources of some of the research institutions. |
