The Quick-RNA Miniprep Plus Kit is an innovative and versatile product designed for the easy, reliable, and rapid isolation of DNA-free RNA from cells, all tissue types, whole blood, and biological fluids. The provided DNA/RNA Shield stabilizes samples, allowing them to be stored without the need for immediate freezing or processing for up to one month. Furthermore, DNA/RNA Shield inactivates RNases as well as microbial pathogens (viruses, bacteria, etc.). The procedure combines a unique buffer system with Zymo-Spin Column technology to yield high quality total RNA (including small RNAs 17-200 nt).
