EB Pure Agarose Gel Extraction Kit is designed for extracting desired DNA fragments from Agarose Gel. The key to this system is the high binding matrix that specifically, but reversibly, binds DNA or RNA under optimized conditions allowing proteins and other contaminants to be removed. Then nucleic acids are easily eluted with deionized water or a low salt buffer. This kit is used to recover DNA fragments between 70 bp and 20 kb with yields exceeding 85%. The recovered DNA is suitable for ligations, PCR, sequencing, restriction digestion, or various labeling reactions.
