biospin gel extraction kit provides a simple, rapid and effective method to purify dna fragments from agarose gel in tae or tbe buffer. dna fragments ranged from 60bp to 23kb are purified from (up to 3% standard or high/low-melt) gel using spin column. purified dna can be used directly for kinds of downstream molecular biological experiments such as cloning, sequencing, restriction enzyme digestion and so on.
