● 储存条件和效期:
室温保存,12个月内有效。缓冲液IL与缓冲液 IB可能有沉淀产生,37℃水浴溶解后即可。RNase
A和蛋白酶K常温运输,-20℃保存。
● 产品简介:
该试剂盒采用独特的裂解液能够有效除去多糖多酚等,能够从昆虫、软体动物、节肢动物、蛔虫等样品中提取DNA,保存在醇类的样品也适用于本试剂盒的提取。一次操作可以处理小于50mg组织,样品经裂解液消化,氯仿分离除去大部分的多糖多酚,再经分离柱进一步纯化,便可得到高纯度的DNA。所得的DNA可以用于PCR,Southern杂交,酶切消化等实验。
● 准备工作:
1. 准备65℃水浴;无水乙醇;制冰机;1.5ml离心管;2ml离心管
2. 按照标签所示在缓冲液IB中加入异丙醇,在DNA Wash Buffer和缓冲液WB中加入无水乙醇,混匀后盖紧瓶盖后常温贮存备用。
3. 每次使用前请检查缓冲液IL,缓冲液IB是否有沉淀生成,如果出现沉淀,37℃温浴至沉淀溶解后再使用。
● 标准操作步骤:
如非指出,所有离心步骤均为使用台式离心机在常温下离心。
1. 液氮充分研磨样品。
2. 收集研磨成粉末的50
mg样品,置于1.5ml离心管中。
3. 加入350 μl65℃预热的缓冲液 IL,并加入20 μl 蛋白酶K剧烈地漩涡振荡,确保所有的组织团都分散均匀。
4.65℃水浴20-30min。水浴期间颠倒样品数次。
5. 加入300 μl缓冲液LF,充分混匀,12,000 rpm (~13,400×g )
离心5分钟。
6. 小心地把上清液吸至另一新的1.5ml离心管中。注意确保不要打散沉淀团或把组织碎片也一起转移。
7. 加入4 μl
RNase A,涡旋混匀。常温放置2min。
8. 加入等体积的缓冲液
IB(请确保已经按照标签加入异丙醇),充分混匀。如:向300μl上清中加入300 μl 缓冲液 IB。
9. 把上述混匀的液体转移到吸附柱CG上。10,000×g离心1
min以结合DNA,弃去滤出液体。纯化柱最大容量为750 μl,如果混合液大于750 μl,请分两次过柱。
10. 将吸附柱重新套回收集管中,加入500μl
缓冲液WB(请确保已经按照标签加入无水乙醇)至柱子中,10,000×g离心1min,倒弃流出液;
11. 将吸附柱重新套回收集管中,加入600μl
DNA Wash Buffer(请确保已经按照标签加入无水乙醇)至柱子中,10,000×g离心1min,倒弃流出液;
注意:DNA
Wash Buffer使用前须按要求用无水乙醇稀释。如果放入冰箱中,使用前须恢复到室温。
12.再加入600 μl
DNA Wash Buffer(请确保已经按照标签加入无水乙醇)至柱子中,8,000×g离心1min,弃去流出液;
13. 将吸附柱重新套回2ml收集管中,最大转速(>13000×g)离心空结合柱1min以干燥柱子的基质;这一步对下面的洗脱步骤至关重要。
14. 将柱子置于1.5
ml灭菌离心管,加入50-150 μl 65℃预热的洗脱缓冲液EB至柱子的膜中央。常温静置5 min;
15. 常温下,离心(>13000g)1min,以洗脱DNA。保留含DNA的流出液。将DNA储于-20℃。
● DNA浓度及纯度检测:
基因组DNA片段的大小与样品保存时间、操作过程中的剪切力等因素有关。提取的DNA片段可用琼脂糖凝胶电泳和紫外分光光度计检测浓度与纯度。可配制0.8-1.0%琼脂糖凝胶,使用λ/HindIII判断基因组的大小,完整的基因组大小应在23 kb以上。使用分光光度计检测时, OD260/OD280比值应为1.7–1.9之间,如果洗脱时不使用洗脱缓冲液,而使用去离子水洗脱,比值可能偏低,但并不表明DNA纯度不高。
常见问题
|
可能原因
|
建议
|
堵柱子
|
转移裂解上清时,转移了沉淀
|
按说明书操作,缓冲液LF分离后,确保不转移到沉淀
|
样品太粘稠
|
样品量别超过说明书上所说的,或者增加缓冲液IB的用量。
|
低浓度的DNA量
|
样品的破壁方式不对
|
不论新鲜还是干燥样品,在加入缓冲液IL之前必须用适当方式的研磨成粉末。
|
样品的裂解效果不好
|
减少样品量,或者增加缓冲液IL的用量。
|
DNA残留在柱子上
|
增加洗脱液EB的用量,并在离心洗脱前将洗脱液EB65℃孵育5min。
|
DNA洗涤不当
|
DNA
Wash Buffer按说明书用无水乙醇稀释。
|
下游应用不好
|
提取的DNA含盐量高
|
DNA
Wash Buffer必须按要求用无水乙醇稀释,必须常温放置。
|
提取的DNA含有乙醇
|
洗脱前,必须最高转速空甩柱子1 min。
