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 RNA Kits are RNA purification kits that provide a streamlined method for the purification of up to 10 µg (per well) of high-quality RNA directly from samples in TRI Reagent®. Total RNA, including small RNAs (17-200 nt), is effectively isolated from a variety of sample sources (cells, tissues, serum, plasma, blood, biological liquids, etc.) using this product. The extraction method inactivates viruses and other infectious agents. The procedure is easy: simply apply a sample in TRI Reagent® to the Zymo-Spin I-96 Plate, then bind, 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 RT-PCR, transcription profiling, hybridization, etc. The entire procedure typically takes about 30 minutes (per 2 plates).

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.

“No phase separation was needed, but you still had the benefits of a Trizol extraction. No need to precipitate and resuspend samples, which means less sample loss during purification.”

- Adina B. (University of Guelph)

“This kit is amazing, I've got a gel comparing the lack of gDNA as shown in the advertising pamphlet. What can I say, except: I love this product!“

- R.K. CSU

“Direct-zol is the most excellent kit for RNA isolation that I ever used in the past 20 years.”

- H.Z. (Harvard Medical School)
