EasyPrep Genomic DNA Kit is based on silica-membrane technology and a special buffer system for many kinds of sample gDNA extraction. The spin-column made of new type of silica membrane can bind DNA optimally on given salt and pH conditions. Simple centrifugation processing completely removes contaminants and enzyme inhibitors such as proteins and divalent cations. Purified DNA is eluted in low-salt buffer or water, ready for use in downstream applications. DNA purified by EasyPrep Genomic DNA Kit is highly suited for restriction analysis, PCR analysis, Southern blotting, and cDNA library.
