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. DescriptionThe Direct-zol™-96 MagBead RNA kit provides a high-throughput (96-well),magnetic bead-based isolation of high-quality RNA directly from samples in TRIReagent® and similar.The extraction method inactivates viruses and other infectious agents. Total RNA including small/microRNAs (≥17 nt) are effectively isolated from a variety of sample sources (cells, tissues, biological liquids, etc.). The procedure is easy: simply add ethanol and MagBinding Beads to a sample in TRI Reagent®, 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 Next-Gen sequencing, RT-PCR, transcription profiling, hybridization, etc.Learn More Technical Specifications CompatibilityTRIzol®, RNAzol®, QIAzol®, TriPure™, TriSure™ and all other acid-guanidinium-phenol based solutions can be used in place of TRI Reagent®.EquipmentMicrocentrifuge, vortex, magstandSample InactivationTRI Reagent® (provided with R2101, R2103, and R2105) inhibits RNase activity and inactivates viruses and other infectious agents.Sample SourceAny sample stored and preserved in TRI Reagent®, TRIzol® or similar (animal cells, tissue, bacteria, yeast, fecal, biological fluids, and in vitro processed RNA (e.g., transcription products, DNase-treated or labeled RNA)).Size RangeTotal RNA ≥ 17 ntYield10 µg RNA (binding capacity), ≥ 30 µl (elution volume)Product FAQ Q1: Is Direct-zol suitable for very small numbers of cells? Yes, the Direct-zol MicroPrep (#R2060) is designed and capable of purifying RNA down to single cell inputs (picogram amounts). A sensitive quantification method is needed (e.g. Qubit, qPCR, etc.) Q2: Is DNase I available for individual purchase? All kit components are available for purchase separately. Q3: How to store DNase-I following resuspension? Lyophilized DNase I is stable at room temperature. Once resuspended, store frozen aliquots. Minimize freeze thaw cycles as much as possible. Freeze thaw will lower DNase activity. Q4: Is the DNase-I treatment necessary? If the downstream application requires DNA-free RNA, we recommend performing the DNase I treatment. Q5: Is the kit compatible with samples stored in DNA/RNA Shield? Yes, bring samples homogenized and stored in DNA/RNA Shield to room temperature (20-30ºC). Add 3 volume of TRIzol/TRI Reagent and mix well. Proceed with RNA Purification. Q6: Is it possible to extract proteins with the Direct-zol RNA kits? Yes, proteins can be Acetone Precipitated post RNA binding step. Please request supplementary protocol from Zymo Research Technical Support. Q7: Can samples be stored in TRIzol/TRI Reagent prior to processing? Yes, samples in TRIzol/TRI Reagent or similar are stable overnight at room temperature and can be stored frozen (-80C). Be sure to lyse and homogenize the sample well prior to freezing. Bring the sample to room temperature prior to RNA Purification. Q8: Is it possible to isolate DNA with the Direct-zol RNA kits? Direct-zol DNA/RNA (D2080) kits can isolate DNA from TRIzol Q9: Is the RNA suitable for Next-Gen sequencing or other sensitive downstream applications? Yes, the RNA is high quality (A260/A280 >1.8, A260/A230 >1.8) and suitable for any downstream application, including NGS, RT-PCR, hybridization, etc. Q10: Which phenol-based reagents are compatible with Direct-zol? The Direct-zol kits are compatible with TRI Reagent, TRIzol, Qiazol, RNAzol, TriPure, TriSure, etc., and any other acid-guanidinium phenol-based reagents. Q11: What is the difference between the Direct-zol RNA and Quick-RNA kits? Direct-zol is for samples stored/collected into TRIzol/similar reagents. Quick-RNA is for all other samples. Q12: What is the difference between the Direct-zol RNA MiniPrep and the Direct-zol RNA MiniPrep Plus? Both kits function the same, the only difference is the RNA binding capacity of the column provided with the kit. Q13: I ran out of RNA Wash Buffer. Can I use something else? Yes, use 80% ethanol as a substitute. RNA Wash Buffer is also sold separately.Product Video Citations 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)Read More“Direct-zol is the most excellent kit for RNA isolation that I ever used in the past 20 years.” -H.Z. (Harvard Medical School)“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“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)“The yield and the purity of the RNA is something out of this world, about at least 50% more RNA and purity not less than 1.95, we never got [that] before with other vendors such Invitrogen, Qiagen, etc.” -Ehab S. (University of Iowa)“The Direct-zol RNA MiniPrep showed the highested recovery [of miRNA] from both cell culture and frozen post-mortem human brain tissue when compared to miRNeasy, mirVana and RNeasy Plus.” -O.E.
