MEGAquick-spin™ PCR 产物与胶回收试剂盒

产品信息
本试剂盒是既可从琼脂糖凝胶中,又可从PCR反应或其它各种酶促反应液中纯化单链或双链DNA片段的试剂盒

本试剂盒是既可从琼脂糖凝胶中,又可从PCR反应或其它各种酶促反应液中纯化单链或双链DNA片段的试剂盒,可有效除去酶蛋白、寡聚核苷酸引物、盐离子、dNTP等。吸附柱内采用独特的吸附材料,与常用硅胶膜相比,可更加GX、专一地吸附核酸分子。

使用本试剂盒操作简单方便,无需使用NaAC调节pH值,每次可纯化多至10μg的DNA片段(≥100bp),纯化得率高达60~90%,可用20μl洗脱缓冲液进行洗脱,纯化得到的DNA片段可直接用于连接反应、PCR扩增、DNA测序等多种分子生物学实验。

主要特点:
1、独特的吸附材料:可更加GX、专一地吸附核酸分子;
2、纯化得率高:高达60~90%,可纯化10μg的DNA片段(≥100bp);
3、纯度高:1.8<A260/A280<2.0,保证后续实验结果的可靠性和重复性;
4、操作简便、快速,只需15min即可完成全部操作;
5、使用安全:无须使用苯酚、氯仿等有毒试剂;
6、一盒两用:既可从PCR反应或其它各种酶促反应液,又可从中琼脂糖凝胶中纯化单链或双链DNA片段。
主要应用:
既可从PCR反应或其它各种酶促反应液,又可从琼脂糖凝胶中纯化单链或双链DNA片段,适用于一般常规分子生物学实验。
存储条件:
本试剂盒在室温(15-25℃)条件下可保存一年。

Description
 
The MEGAquick-spinTM PCR & Agarose Gel DNA Extraction Kit is designed to recover or concentrate DNA fragments (87 bp~20 kb) from agarose gels, PCR or other enzymatic reactions. Up to 95% recovery is achieved depending upon the fragment size. PCR products are commonly purified to remove excess nucleotidesprimers.
 
 
Characteristics
 
1) Allows purification directly from PCR reactions or agarose gel slices
2) Purify DNA fragments or PCR products in as little as 20 minutes.
3) Up to 95% recovery of ready-to-use DNA.
4) Purify DNA fragments (87 bp~20 kb).
5) Purified DNA fragments are ready to use for PCR, sequencing, restriction digestion.
