The family of Wizard® SV and SV 96 Systems offers optimized reagents for isolation of numerous nucleic acid types, including plasmids, DNA fragments, genomic DNA, PCR products and total RNA. The SV technology uses a silica-impregnated porous membrane to bind DNA or RNA, separating it from contaminants. These membrane-based systems offer several advantages over silica resin columns, including better washing and drying characteristics and greater processing speed.
