DNA fragments for probe DNA or ligation must be separatedpurified from other DNA fragments. MEGA-spinTM employs a column method to purify target DNA in excised agarose gel. The column method uses a highly concentrated salt solution to keep the target DNA bound to the column membrane. The binding reaction occurs due to the disruption of the organized structure of water moleculesthe interaction with the nucleic acids. Thus the adsorption to the specifically pretreated membrane is favored. Since the binding process is specific for nucleic acids, the bound material can be separatedpurified from impurities e.g. saltsproteins, with simple washing step. Nucleic acids elute from the column membrane in a low salt buffer or water.

MEGA-spinTM is designed to extractpurify DNA of 100bp to 10kb from standard or low-melt agarose gels in TAE or TBE buffer. Furthermore, the kit guarantees a high yield of purification up to 70-90%. DNA fragments isolated with MEGA-spinTM Agarose Gel Extraction Kit are efficiently ligated into plasmid cloning vectors or specifically labeled using either random primed labeling or nick translation. No inhibition of digestion with restriction endonucleases is observed.

2. Recovery of DNA from different PCR product size
Purification of DNA fragments with the MEGA-spinTM Agarose Gel Extraction Kit is based on solubilization of agaroseselective adsorption of nucleic acids onto MEGA-spinTM silica-membrane in the presence of charotropic salt. The different sizes of DNA fragments can be extracted from gels in 70%-90% recovery.
