The kit provides a very simple, fast and economic way for the isolation of PCR-ready genomic DNA from soil, adopting the Genomic DNA Buffer Set. The simple purification procedure, based on the remarkable selectivity of Biospin membrane, allows isolation of high yields genomic DNA less than 30minutes. It does not require expensive equipment, involves only few steps, and completely avoids the use of toxic and hazardous reagents such as phenol and chloroform.

At first, the soil sample is lysed by SP buffer and Lysis S Buffer in the grind tube. Designed for using with the lysis instruments from BIOER,soil is easily lysed within 40 s.Also manual operation can be chose with vortex generator within 5minutes.

Then DNA in the sample is liberated. After centrifuging, the impurity will be discarded. Released DNA is bound exclusively and specifically to the Biospin membrane in presence of a Binding Buffer under appropriate salt iron and pH conditions. Denatured protein and other contaminants are removed by several washing procedures. The DNA is then eluted from the membrane with the Elution Buffer.
