Gel purification of DNA is a common technique used for the isolation of specific DNA fragments from reaction mixtures. However, most methods either fail to completely remove the agarose (which can lead to problems in downstream manipulations), shear the DNA, or results in very low yields. The Solar.® Gel Extraction kit uses HiBind® DNA spin-column technology to recover DNA bands 100bp-20 kb in length from all grades of agarose gel with yields up to 85%. The DNA band of interest is excised from the gel, dissolved in BDP Buffer, and applied to a DNA HiBind® spin column. Following three wash steps, DNA is eluted with deionized water or EB Buffer and is ready for downstream applications

such as ligations, PCR amplification, restriction enzyme digestion and various labeling reactions. This kit can be also used to purify DNA fragments from PCR products and enzymatic reactions. Two spin column formats  are  are available for this kit.
