Life Magnetics, Inc. has developed a carbon-based surface chemistry for RNA extraction: graphene based magnetic bead for RNA diagnostics, theraputics, and research. The carbon surfaces are selective for single stranded nucleic acids and isolate RNA sequences with better purity and yield than silica-based magnetic bead kits. Carbon-based purification kits exhibit no detectable DNA contamination (lane 1 and 2). Silica-based RNA isolation kits show heavy DNA contamination (lane 3); even after treatment with DNase (lane 4). The firm's purification kits yield high purity RNA suitable for analysis by methods such as RNA sequencing, northern blot analysis, and RT-qPCR.
