This Bionano Prep SP Blood and Cell Culture DNA Isolation Kit can provide ultra-high molecular weight (UHMW) gDNA in less than 4 hours for EDTA-collected blood and mammalian cell cultures. It utilizes a lyse, bind, wash, and elute procedure that is common for silica-based gDNA extraction technologies in combination with a novel paramagnetic disk. Unlike magnetic beads and silica spin columns, which shear large gDNA, the Nanobind Disk binds and releases gDNA with significantly less fragmentation, resulting in UHMW gDNA.
