QuickClean II Gel Extraction Kit offers a simple, rapid and effective method to extract and purify DNA from agarose gel in TAE or TBE buffers. This kit is designed to increase the recovery of DNA fragments from 60 bp to 23 kb DNA fragments which are purified from up to 3% standard or high/low-melt agarose using spin column. The extracted DNA can be used directly for kinds of downstream molecular biological experiments such as cloning, sequencing, restriction enzyme digestion and so on.
