Principle
应用Gentra Puregene Kits,细胞用阴离子洗涤剂裂解,其中加入DNA稳定剂。DNA稳定剂限制胞内及其他环境中的DNases的活性。使用RNA降解酶去除RNA。蛋白质等其他污染物经盐析沉淀法去除。最终,通过乙醇沉淀回收基因组DNA,水合溶液(1 mM EDTA、10 mM Tris·Cl pH 7.5)溶解DNA。一般情况下,纯化的DNA的A260/A280值在1.7–1.9之间,大小可达200 kb。纯化的DNA可贮存于2–8°C、–20°C或–80°C,确保安全。
Procedure
可存档的DNA
DNA的纯度对下游应用结果的精确性至关重要,诸如PCR等敏感的下游应用要求使用最高品质、且分子量尽可能大的DNA,以确保可靠的结果。Gentra Puregene Kits去除污染物和酶抑制剂,确保获得高度稳定的适合存档的DNA。纯化获得高品质的DNA,分子大小为100–200 kb。
Applications
应用Puregene Accessories和Gentra Puregene Kits纯化的DNA高度稳定,适用于各种下游应用,包括:
DNA存档
PCR
SNP分析
Southern印迹
