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).

“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)
