The purified RNA is free from any protein-bound circulating RNA, and can be used in a number of downstream applications including real-time PCR, Northern blotting, RNase protection, primer extension, expression arrays, and next-generation sequencing. Finally, the company also launched four kits for the depletion of exosomes from fetal bovine serum.
