Great kit, but not great with fatty tissues.
Rating: 4.7

  • Application Area:Analyzing RNA from cells or tissue

"This kit is amazing, but it has one technical issue. I used it for placental samples dissolved in RNAzol. The high fat of the samples make the column completely hydrophobic so water would pass after a spin down, but no RNA would be eluted. Outside of this instance, I've never had an issue."

Rating: 5.0

  • Application Area:Lysis of zebrafish tissue samples

"Product is extremely easy to use for degradation-sensitive material, is much less risky for exposure and contamination of phenol-related waste compared to traditional RNA extraction methods. Easy for undergraduates to use. High yield of RNA, high quality and works well for RT-qPCR directly."

Works fine but might require an additional RNA purification.
Rating: 4.7

  • Application Area:RNA extraction

"This kit is really easy to use. It's also quite fast! I like that it allows you to use samples already prepared in TRIzol. So I can homogenize my samples in TRIzol and store them at -80C until I am ready to proceed with RNA extraction. The downside is that in like 50% of time (10 out of 20 samples) I got a very bad 260/230 ratio (0.94-1.5) so I had to do additional RNA purification step. In short, I would say, yes, I recommend it if you are ready to perform an additional RNA precipitation or column clean-up step."

Great results and clean RNA!
Rating: 5.0

  • Application Area:Isolate RNA for the use in real-time PCR

"The RNA prep kit is excellent for yielding clean RNA in a user-friendly way. The steps are simple and easy to follow and were easily adapted with the RNA isolation protocol that was already in place. This kit is also great for RNA isolation from tissues; once the tissue is homogenized in the Trizol reagent, it can be spun to separate the aqueous phase before just following the rest of the Zymo protocol. The RNA is very clean every time and I am able to use a lower concentration of RNA for each PCR reaction!"

  • Application Area:Analyzing expression level of mutant proteins in cancer cell line.

"Direct-zol was a windfall for my research project! After spending months generating stable mutants, I then had to analyze target protein levels with and without chemokine treatment. As my P.I. usually prefers the "old-world" method and anything found Maniatis et al, I was originally directed to use a more common tri-reagent. However, the results were not reproducible. After spending weeks convincing the P.I. to get the Direct-zol kit, they relented, and it was so worth it. It is so much easier than handling large lysates, and reproducible every 3 times! The after sales care is pretty simple, just follow the reagent storage conditions. The bang for your buck is stellar because you get the answer you need and CAN MOVE ON! The only thing I can mention is that it may be worth eluting in two steps (no additional volume needed, just use 1/2 volume RNAse free water and soak column for 1 minute before spin-down, then repeat allowing 1-minute soak.)"

Great results for cell culture, not so good for human placental samples
Rating: 4.3

  • Application Area:Placental samples

"This kit works amazingly with cell culture samples; however, RNA extracted from placental samples did not work. I think it was the high fat content. This made it so the elution buffer or water would not absorb into the column at the final stage. The water simply beaded on top of the column and still passed through upon centrifugation, but no RNA was eluted. This has only happened for placental samples in my hands and forces me to use phase separation. There was no indication this could happen in the manual."

The best one in the market
Rating: 5.0

  • Application Area:Plant Science, cell molecular biology

"During my ten years of experience in the lab, I have tried all gel purification kits in the market (seriously)! From the cheaper to the most expensive ones, the easy to the complicated ones, non-branded to the well-known brands. However, I can summarize that the easiest, highest-yielding, quickest, and most affordable kit is definitely by Zymo Research, and every time I recommended it to other labs."

"The RNA kit is easy to handle and fast to use. Otherwise we only use Trizol, but this time we switched to a kit from Zymo Research. The RNA yield was very good, the quality too.

Great experience, made our experiments successful.
Rating: 5.0

  • Application Area:Molecular signaling pathway analyzing in cortex and neurons

"We got a very good quality of RNA from limited amount of specific area in cortex. The price of the kit is very good for research experiments. Moreover, the protocol is much easier to carry out and saves a lot of time. It does not require the centrifuge to be cooled to 4 degrees any more, which is very convenient for most labs. Our students like the kit very much compared to the previous classical one. We would like to order more in future."

Trizol improved with Direct-Zol.
Rating: 5.0

  • Application Area:Analyzing microRNA expression in tissue and cell lines

"We have been using Trizol following the manufacturer indications to extract RNA from tissue and cell lines. However, we wanted to improve the extraction in terms of purity while reducing the hands on time. We found out about Direct-Zol and tested it. Our RNA improved in quality and we reduced the time for extraction. In addition there's no need for chloroform addition, which is outstanding."

Very useful kit.
Rating: 4.7

  • Application Area:Analyze mRNA in tissue samples

"Direct-zol has been very effective to isolate total RNA highly purified to use as a template to the synthesis of cDNA. For purposes to amplified samples by qPCR, high quality samples of RNA are obtained easily and quickly. The value for money is very good, the time required, the quantity of sample and the easy way to perform the procedure justify the cost."

  • Application Area:RNA extraction

"I am extremely satisfied using the Direct-zol RNA MiniPrep Plus kit! I no longer have to worry about the days of using the dreaded chloroform/Trizol extraction method which would sometimes take hours to finish. The Direct-zol protocol is easy, efficient, and can be finished in less than 30 minutes! Now I can extract RNA and run a qPCR for the same samples all within the same day! I love using the Direct-zol kit and can't imagine doing RNA extraction without it!"

Great product for RNA related works.
Rating: 5.0

  • Application Area:Measure miRNA and mRNA expression in cells and animal tissues

"We think the protocol that comes with the kit is very easy to read and follow, even first year undergraduate researchers can easily get familiar with the procedures, which increases the lab's efficiency greatly in terms of cutting down the training time. Also it always yields good RNA concentration, for both cells and animal tissues. We deal with mouse colon tissue a lot and due to the small portion we have, we really appreciate this product and its high yield rate with good quality control. Ever since we started to use this product, we have conducted several animal studies and published multiple manuscripts with it, and we will continue using it in future."

Rating: 5.0

  • Application Area:Zebrafish, chicken, development, RT-qPCR, PCR, NGS

"As a developmental biologist in a mostly undergraduate university, I need a product that delivers high-quality RNA in a format that is highly reproducible and cost-effective. My undergrads find the protocol easy to follow as it has far fewer steps than competitors' products. Students' results are more consistent between experiments because of the simpler format. The end product is of high quality and we have used the RNA for qPCR and NGS experiments successfully. My ratings are all five star. The kit is much cheaper than those of other major competitors and after sales service is excellent."

"This kit helps me transfer from traditional trizol purification steps with simple column loading and washing. It is cool! I do have a suggestion: is there any possibility to omit the extra DNase digestion step and provide a more efficient DNA elimination column before RNA purification column?"

Great Results: the perfect complement to Trizol.
Rating: 4.7

  • Application Area:Purification of DNA and RNA from insect tissue

"This is a great easy to use kit to purify high quality DNA and RNA from the same sample. It saves time and allows us to do multiple analyses with 1 sample. This kit is much simpler and faster than purifying DNA and RNA from Trizol without this kit and I think the columns give you a more pure product than traditional pelleting."

  • Application Area:Isolation of RNA from tissue in Trizol

"I achieved excellent and reproducible results with the use of the Direct-zol RNA Miniprep Kits. My samples were very delicate and "precious" and with the normal RNA extraction techniques I had not obtained sufficient yields for the subsequent analysis (NGS). The extraction protocol is very simple, I didn't need to contact sales assistance and it is convenient as far as value for money."

  • Application Area:Isolation of total RNA from E. coli

"The product's protocol is extremely easy to follow and the yield/purity of the RNA is impeccable. I only use this RNA isolation kit for cDNA library construction for Next Generation Sequencing projects. The product, compared to other companies', is fairly priced. Interacting with customer service regarding troubleshooting or questions about the product was one of the best experiences I had. Zymo research's customer service operators go above above and beyond to help resolve the any issues. Honestly, it is worth purchasing any item from Zymo research because of the really amazing customer service. It is absolutely worth spending money with Zymo research because of the company's customer service and high quality of their products. I am very pleased with the products I purchased from Zymo Research and will continue to both purchase more products and recommend the company to others!"

  • Application Area:Real-time PCR

"This is a super simple, easy, and highly efficient product. I've never failed since I started using this product. It is just so easy and saves your time. You will always expect a high yield for even a small amount of cells. In most cases, for my flow cytometry sorted cells, I can only have around 0.05 to 0.1 million, but it is enough for me to get a high quality of total RNA. It is fantastic product."

"I have always used Zymo products due to their ease of use and high quality results. I work exclusively with undergraduates and the directions are clear and easy to follow. I can even get whole classes to work through the protocols together - a little like herding cats. The students really have to work to mess up the protocols and they rarely do."

"This is a great kit for the isolation of RNA from tissues and cells. I have personally used it for isolation of RNA from drosophila ovaries and drosophila cells. The kit gives pure RNA from these samples. Also useful for isolating small RNA samples as RNA molecules as small as 17 nucleotides can be purified. The amounts of RNA is also reproducibly high. The in-kit DNase treatment also works well to eliminate all DNA."

"I used this kit for isolation of RNA out of small pieces of mouse aorta. The amount of RNA was okay, the RNA integrity was good (as high as 5).

Rating: 5.0

  • Application Area:Analyze small RNAs in Corals and their symbiont

"After trying some kits for small RNA extraction, I finally find this one. Working with corals (non-model organism) is not easy, the amount of RNA it is dependent on the amount of calcium skeleton I can get rid of. I usually get a small amount of tissue. With these kit I extracted consistently an amazing RNA yield (~20ug) from 500 ug of coral tissue :D . The quality is great, beautiful peaks in the Bioanalyzer, even though with other kits I always got very small amount and not with this excellent quality. I really like to work fast when extracting RNA. This kit is super easy to work and will save you a ton of time. "

Review date: 12 Jul 2016 | Direct-zol™ RNA Miniprep Plus

The Direct-zol RNA Kits provide a streamlined method for the purification of up to 100 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 (see below).

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.
