Great results, easy to use, worked well.
Rating: 5.0

  • Application Area: Extracting RNA from cells in culture

"Anyone who has tried RNA extraction from tissue/cell lines can attest to the frustrations that may be present throughout the process. From low yield to degradation, RNA extraction can be very challenging using any method. This kit was surprisingly easy to use, and gave great results. Will definitely be purchasing the full kit for future use."

Low yield from biofilmy bacterium, good yield from green alga..
Rating: 4.7

  • Application Area:Transcriptomics

"Unfortunately, this kit did not allow me to purify sufficient RNA from a tough-to-lyse bacterium that makes some unknown biofilmy stuff. However, it did result in high yield RNA from the alga chlamydomonas reinhardtii, albeit the quality assessed via bioanalyzer trace was just OK (not perfect)."

Great yields, minimal time and authenticated downstream application results.
Rating: 5.0

  • Application Area:Using for TaqMan Assays for cytokines

"I have used so far 10 Direct-zol RNA Miniprep Kits to purify RNA from adherent and suspension cell samples lysed in Trizol and always performed the optional on-column DNAse digestion. The yields were extremely good, most samples show RNA yield more than expected over OD 260/280 2.0. I stopped using big brand kits, which take a much longer time to purify with lower yields and this Direct-zol RNA Miniprep Kit seemed like such a convenient alternative."

DirectZol is wonderful for RNA isolation and transcription reaction cleanup.
Rating: 5.0

  • Application Area:Direct isolation of RNA from Trizol lysates; isolation of capped mRNA

"I find the Direct Zol RNA isolation kit the fastest, easiest, and highest yielding method for isolation of RNA from Trizol extracted Drosophila tissue lysates. So much easier than centrifugation followed by phase separation. I've also started using the kit to clean up capped mRNA T7 ARCA transcription reactions, and the yields are wonderful! Usually get 600 to 700 ng/microliter of clean useable mRNA for insect transgene injections. I highly recommend this product."

Easy and simple, High yield and high quality of RNA prep kit.
Rating: 5.0

  • Application Area:Total RNA extraction from live cells after FACS sorting

"We’ve been working to generate pipeline with bulk RNA seq. Our lab tried several kits from different companies, then decided to purchase the entire kit from Zymo after trying a sample kit. This kit gave us highest amount of RNAs with hight quality for RNA-seq from both whole tissue and cells collected from FACS. The columns works perfect with Trizol agent-which is the most common reagent and in-column digestion to remove DNAs was another benefit! Easy to follow the directions and reasonable price for 50 preps, compared to other competitors. Highly recommend."

Fantastic package! Simple to use and extremely dependable in terms of performance.
Rating: 4.3

  • Application Area:Pathway analysis in Yeast Cells

"This is a very simple and fast product for RNA extraction from a variety of yeast cells. Postgraduate and PhD students routinely isolate mRNA from several yeast species. We tested several species from Pichia, Candida, Saccharomyces, and Komagataella. On average we get RIN value of 9 for the isolated RNA which is great for our downstream applications expression analysis. The recovery is good too, with yield ranging from 850-1000 ng/ul RNA. We simply love the on column DNAase digestion, clean up in 45 minutes. Above all, the price per sample fits to our budget. With wide range of distributors we get this product in the remote area in weeks. It fits the bill perfectly."

"Overall, I think this is a great product. It is easy to use and the steps are pretty clear. You can't beat the price either. My only negative comment is that the DNase doesn't seem to work very well. Our labs ended up buying it from another supplier and just using it with this kit."

Quick isolation of RNA for sequencing or PCR.
Rating: 4.3

  • Application Area:RNA isolation for sequencing

"The product comes easy to use, with minimal steps after trizol application to 2D tissue culture on plastic or glass. The purity comes out pretty close to what is reported, although it seems less consistent when cell counts are lower. Time of isolation is cut significantly. I think it is worth it if you are willing to pay a premium compared to traditional methods of isolation."

Rating: 4.3

  • Application Area:Lymphocyte mRNA extraction

"The procedure is clear, easy to carry out, the amount of mRNA was lower than expected and the quality was regular, we are in the standardization phase, I hope that once the points to be corrected have been identified, the performance of the insert can be achieved."

Reliable product and wonderful service.
Rating: 5.0

  • Application Area:RNA extraction and qPCR

"It’s a very good and reliable product. We use it to extract RNA from fungal samples, and it’s quite easy to use and compatible with trizol stored samples. The only thing is that we tend to have to do a second round of DNAse digestion to remove trace amount of gDNA contamination. The customer service is very nice and once they even offered to fill up our back ordered kit with free samples (didn’t go for that but really appreciate their kind gesture to do anything possible to care for the customers). RNA quality off the column is always good."

Very reliable product and easy to use.
Rating: 5.0

  • Application Area:Define expression level in Candida Albicans

"This is a very good product that was recommended by my colleagues. It is suitable for the extraction of yeast/Candida total RNA from samples stored in Trizol. It is very easy to use, takes around 30-40 total to finish the extraction, on column DNase digestion and the final concentration reading. The recovery is good too, I ususally get 800-1000 ng/ul RNA from the column. One thing to notice that is these columns do have maximum capacity. Since we tend to have slightly higher cell numbers to apply to the column, we have used an additional ‘in the tube’ DNase digestion step to make sure the complete removal of gDNA contamination. We also purchase the columns separately just for regular RNA cleaning procedure. All the qRT results look quite good."

"The quality I am looking for in PBMC is usually as high as possible in both ratios 260/280 and 260/230 because these samples are usually sent for sequencing and many of them are nor replaceable. This kit, in addition to be easy to use and to explain to others, ensure high yields and ratios if it is used properly. Highly recommended to use!"

I like this product so much, saving me from RNA extraction.
Rating: 5.0

  • Application Area:RNA extraction from tissue samples

"1. It's easier to use with column filters than regular Trizol extraction of RNA. DNase I included guarantees the quality of RNA without DNA contamination, good for various downstream applications. Also, the small RNA is collected and can be used for more comprehensive RNA profiling. 2. I remember once I contacted the technical support for some questions, I got the reply pretty quick. That makes me more confident in the company's devotion on customers. 3.The price is more competitive compared to other companies, considering the performance and easiness."

NGS quality RNA without losing precious time.
Rating: 5.0

  • Application Area:RNA within minutes, NGS quality

"I had tons of RNA in trizol and was looking for a spin column alternative instead of the usual precipitation. I came across this kit and order a sample kit. This is simple to use without the fear of RNASes. Plus the DNASe is provided as well which is a good touch. I also ended up doing a bioanalyziner and the RIN was always been 8-9 which was brilliant. (Plus one sample was in trizol for more than a year and the RIN was 9). I did some NGS with these samples and was satisfied. Can't complain, thumbs up!"

Works well and always gave good quality RNA.
Rating: 5.0

  • Application Area:Extract RNA from tissues that are hard to extract from

"I used this kit with a modified method, still doing phase separation with tr-regent and then putting the aqueous layer through the column in this kit. That worked really well for me and gave consistently good RNA. This modified protocol worked for polysaccaride rich tissues - mytlus mussel species that needed some extra care to extract good RNA."

Obtained great results relative to equivalent kits from alternative vendors.
Rating: 4.7

  • Application Area:RNA isolation for qPCR

"The kit combines ease of use and speed together with the ability to isolate high concentrations of high quality RNA, with little to no contaminating DNA that could interfere with downstream applications such as RT-PCR and microarray analysis. It worked well for both Gram-negative bacteria (E. coli and S. typhimurium) and hard to lyse mycobacterial species, such as M. tuberculosis."

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."

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."

"During my ten years of experience in the lab, I have tried all gel purification kits in the market (seriously)!

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."

"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.

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."

"RIN =10 for all RNA preparations, good yield of miRNAs, results are highly reproducible, kit is easy to use. It is compatible with any lysis buffer.

I really like this kit & recommend for anyone to use over acidic phenol or other kits.
Rating: 5.0

  • Application Area:RNA collection from mammalian cells to reverse transcribe DNA.

"The kit was very easy and a welcome change from acidic phenol. I was surprised how good the yield and quality of the RNA was. The RNA was great and I obtained the reverse transcribed DNA the first time and it was easy to subclone."

Great result, super easy!
Rating: 5.0

  • Application Area:Evaluation of mRNA levels for certain signaling pathways

"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?"
