Isolate total RNA and small/miRNA from TRIzol without phase separation


  • Easy Handling: Bypass chloroform, phase separation and precipitation steps.
  • NGS-Ready: Ultra-pure RNA without phenol carryover. No DNA contamination (DNase I included).
  • Non-Biased: Complete RNA recovery without miRNA loss.


The Direct-zol™-96 MagBead RNA kit provides a high-throughput (96-well), magnetic bead-based isolation of high-quality RNA directly from samples in TRI Reagent® and similar. The extraction method inactivates viruses and other infectious agents. Total RNA including small/microRNAs (≥17 nt) are effectively isolated from a variety of sample sources (cells, tissues, biological liquids, etc.). The procedure is easy: simply add ethanol and MagBinding Beads to a sample in TRI Reagent®, wash and elute the RNA. No phase separation, precipitation, or post-purification steps are necessary. The result is broad range purification of small and large RNAs suitable for subsequent RNA-based methods including Next-Gen sequencing, RT-PCR, transcription profiling, hybridization, etc.

Researchers used the Direct-zol RNA MiniPrep for heterologous E. coli expression of the FnCpf1 locus by means of RNA-seq and discovered a new endonuclease, Cpf1, which further improves upon the widely used CRISPR-Cas9 genome editing system. Cpf1 targets distinct PAM sequences, requires no tracrRNA, and cleaves DNA with staggered overhangs.

The Direct-zol RNA Miniprep kit was used to isolate pure total RNA from Rat cells, and the high quality RNA was used to create a cDNA library for RT-qPCR analysis of several genes related to hematopoietic Stem Cell (HSC) Development. The consistent RNA extraction allowed the scientists to determine that HSC cells do not significantly contribute to kidney repair following acute kidney injuries.

High-quality RNA isolated with the Direct-zol™ RNA MiniPrep from fecal and culture samples were shown to be instrumental in the development of a rotavirus early detection system using RT-PCR. The efficient RNA isolation helps in identification of severe gastroenteritis in infants and young children.

“Before I discovered this kit, I was isolating RNA the old school way with chloroform and it would take half the day to finish the protocol. The Direct-zol RNA Miniprep kit is AWESOME! It took hardly any time, the protocol was so easy, and my RNA quality was SO much better. Honestly, this kit revolutionized my life at the bench.”

- A. Newhart (The Wistar Institute)

“Simple protocol and yielded good quality of RNA. Only one kit working for all type of tissue, cell and especially biological fluids.”

- Mohan K. (University of Illinois, Chicago)

“Previously I used a protocol that took 3 hours, now I can have my RNA in 20 minutes. What is not to like about that? Just one column and two buffers, I love it.”

- Arjan V. (Indiana University)
