Classic GenElute DNA purification kits use a silica resin to strongly bind DNA under high salt conditions, allowing proteins, small RNAs, and other molecules to be removed through wash steps using a salt/ethanol solution. After washing, purified DNA is eluted in water or TE buffer. A broad portfolio of GenElute DNA purification kits tailored to specific sample types are available, enabling the purification of genomic DNA (gDNA) from cell culture, mammalian tissue, blood, bacteria, viruses, plant tissue, soil, water, urine, and stool.
