This product can rapidly separate and purify genomic DNA from 200-400 μl of fresh or frozen human or animal whole blood within 15-20 min. The product does not use proteinase K. After the whole blood is dissolved by Solution BFL1,the hemoglobin is removed by Solution BFL2 precipitation. The genomic DNA in the supernatant can be bound to the purification column. After being washed by Buffer RP and Wash Buffer, the remaining proteins on the membrane and the PCR inhibitors are removed,the genomic DNA is eluted by Elution Buffer and can be used in various molecular biology experiments immediately.
