建立了从少量石蜡包埋的组织切片中快速提取石棉肺癌组织中的基因组ＤＮＡ的水煮脱蜡法，克服了传统的二甲苯脱蜡法的周期长、成本高和毒性大的缺点。所得到的基因组ＤＮＡ中，长片段占较大的比例，总量可足够用作１０～２０次ＰＣＲ扩增反应的模板，并可用于其它分子生物学研究 A water-based dewaxing method was developed to rapidly extract genomic DNA from asbestos-containing lung cancer tissue from a small amount of paraffin-embedded tissue sections. This method overcomes the disadvantages of traditional xylene dewaxing methods such as long cycle length, high cost and high toxicity. The resulting genomic DNA, the long fragments accounted for a large proportion, the total amount can be sufficient as 10 to 20 PCR amplification template, and can be used for other molecular biology
