芯片毛細管電泳具有進樣量少，靈敏度高，分析速度快等特點，非常適合法醫DNA-STR的快速檢驗。毛細管電泳芯片由于尺寸小，可施加較大場強，所以在幾秒鐘內就可完成對樣品的分離，微陣列毛細管電泳芯片可實現高通量檢測則成為目前學者研究的熱點。2002年Emrich CA等[31]報道的將高通量384孔毛

1.引言 提取高濃度、大片段、多樣性程度高、具有代表性的土壤微生物總DNA對土壤微生物多樣性研究至關重要。然而，土壤是一個非常復雜的異質體系，其中含有的腐植酸及腐植酸類似物、酚類化合物、重金屬離子等，在DNA提取過程中如不能有效去除，將直接影響后續的PCR擴增、核酸雜交、內切酶消化等分子操作。用傳統

基因組DNA相對穩定，故其提取方法也相對簡單。通常細胞通過表面活性劑處理，釋放出基因組DNA，經過蛋白酶和RNA酶消化后，經有機溶劑抽提和乙醇沉淀或過柱純化即可獲得一定量的基因組DNA。目前商品化的基因組DNA提取試劑盒分為溶液型和離心吸附柱型兩種。溶液型產品價格經濟，產率高，可獲取適用于建立文庫的
