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

Highlights


  • 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.

Description


The Direct-zol RNA MicroPrep Kits are RNA purification kits that provide a streamlined method for the purification of up to 10 µg (per prep) of high-quality RNA directly from samples in TRI Reagent® or similar. 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.). Isolation of RNA by conventional phase separation was shown to selectively enrich for some species of miRNA, leading to bias in downstream analysis. The Direct-zol™ method assures unbiased recovery of small RNAs including miRNA. The procedure is easy. Simply apply a prepared sample in TRI Reagent® directly to the Zymo-Spin™ Column and then bind, wash, and elute the RNA. No phase separation, precipitation, or post-purification steps are necessary. The eluted RNA is high quality and suitable for subsequent molecular manipulation and analysis (including RT-PCR, transcription profiling, hybridization, sequencing etc.). The entire procedure typically takes only 7 minutes.

Reviews


“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)
