The NextPrep™ Magnazol™ cfRNA isolation kit is designed for extracting cell-free RNA (cfRNA) for constructing NGS libraries from human blood plasma or serum, using a fast magnetic bead-based format requiring minimal hands-on time. The isolated cfRNA is ideal for next generation sequencing. Suitability of the RNA for use in NGS library construction has been verified using the NEXTflex® small RNA-Seq v3 library prep kit for Illumina® sequencing.
