The component/product name of Monarch RNA Cleanup Columns has changed to Monarch Spin Columns S1A.
Effective March 25, 2024, component/product name changed to Monarch® Buffer BX.
Effective March 25, 2024, component/product name changed to Monarch® Buffer WX.
The Monarch Spin RNA Cleanup Kit (10 µg) enables fast and simple purification and concentration of up to 10 µg of RNA from enzymatic reactions.
Check out our Technical Note containing comprehensive insights into measuring and analyzing nucleic acids.
The Monarch Spin RNA Cleanup Kit (10 µg) rapidly and reliably purifies up to 10 μg of concentrated, high-quality RNA (> 25 nt) from enzymatic reactions including labeling, capping, in vitro transcription (IVT) and DNase I treatment. This kit utilizes a bind/wash/elute workflow with minimal incubation and spin times. Our unique column design helps ensure zero buffer retention and no carryover of contaminants, enabling elution of sample in volumes as low as 6 μl. Eluted RNA is ready for use in a variety of downstream applications, including RT-PCR, RNA Library Prep for NGS and RNA labelling. The protocol can also be modified to enable the purification of smaller RNA fragments (≥ 15 nts).
Designed with sustainability in mind, Monarch kits use significantly less plastic and responsibly-sourced, recyclable packaging.
Monarch Spin RNA Cleanup Kits are also available for 50 µg (NEB #T2040) and 500 µg (NEB #T2050) binding capacities. Columns are also available separately for convenience.

Problem | Cause | Solution |
---|---|---|
Low RNA Yield | Reagents added incorrectly | Check protocol to ensure correct buffer reconstitution, order of addition of buffers and ethanol, and proper handling of column flow-through and eluents. |
Insufficient mixing of reagents | Ensure the ethanol is thoroughly mixed with RNA sample and RNA Cleanup Binding Buffer before applying the sample to the RNA Cleanup Column. | |
Incomplete elution during prep | Ensure the nuclease-free water used for elution is delivered directly to the center of the column so that the matrix is completely saturated. Larger elution volumes, multiple elutions, and longer incubation times can increase yield of RNA, but will dilute the sample and may increase processing times. For typical RNA samples, the recommended elution volumes and incubation times should be sufficient. | |
High degree of RNA secondary structure | Binding and elution of smaller RNAs (< 45 nt) can be affected by secondary structure of the RNA molecules. If poor yield of a small RNA is observed, we recommend diluting your sample with 2 volumes of ethanol instead of one volume in Step 2 of the protocol. | |
Purified RNA is Degraded | RNase contamination | In order to avoid RNase contamination during RNA cleanup, make sure to work on a clean lab bench, wear gloves and use disposable RNase-free pipet tips and microfuge tubes (not provided). Keep all kit components tightly sealed when not in use. |
Improper storage of RNA | Purified RNA should be used immediately in downstream applications or stored at -70°C. | |
Low A260/230 Ratios | Residual guanidine salt carry-over | Ensure wash steps are carried out prior to eluting sample. Use care to ensure the tip of the column does not contact the flow-through. If unsure, repeat centrifugation. When reusing collection tubes, blot the rim of the tube on a Kimwipe prior to reattachment to the column to remove any residual wash buffer. |
Low Performance of RNA in Downstream Steps | Salt and/or ethanol carry-over | Ethanol and salt remaining after the washes may inhibit downstream applications. Use care to ensure that the tip of the column does not come into contact with the flow-through. If in doubt, re-centrifuge for 1 minute to ensure traces of salt and ethanol are not carried over in the eluted RNA. |
DNA contamination | DNA removal may be necessary for certain applications. Incubate RNA sample with DNase I (NEB https://www.neb.com/en/#M0303) and cleanup RNA using the Monarch Spin RNA Cleanup Protocol. |
