The Monarch Spin RNA Cleanup Kit (50 µg) enables fast and simple purification and concentration of up to 50 µg of RNA from enzymatic reactions.

  • Ideal for cleanup and concentration of RNA after enzymatic treatments including DNase I, Proteinase K, labeling, capping or in vitro transcription (IVT)
  • Efficiently purify RNA ≥ 25 nt (a simple modification enables purification of RNA ≥ 15 nt)
  • Elute in ≥ 20 µl for concentrated RNA
  • 70-100% RNA recovery
  • Can be used to purify RNA from the aqueous phase following TRIzol® or similar extractions
  • Simplified workflow with a single wash buffer
  • Unique column design helps prevent buffer carryover and elution of silica particulates
  • Purified RNA is ready for use in a wide variety of downstream applications, including transfection

    How to recycle your Monarch® Kit components

The Monarch Spin RNA Cleanup Kit (50 µg) rapidly and reliably purifies up to 50 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 helps ensure zero buffer retention and no carryover of contaminants, enabling elution of sample in volumes as low as 20 μl. Unwanted NTPs and short RNA fragments are removed, ensuring highly pure RNA transcripts following IVT/RNA synthesis. Eluted RNA is ready for use in a variety of downstream applications, including RT-PCR, RNA library prep for NGS and RNA labeling. 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 10 µg (NEB #T2030) and 500 µg (NEB #T2050) binding capacities. Columns and buffers are also available separately for convenience.

Figure 2: The Monarch Spin RNA Cleanup Kit enables efficient recovery of RNA in as little as 20 µl

rRNA (50 µg of 16S and 23S Ribosomal Standard from E. coli, Sigma) was purified using the Monarch Spin RNA Cleanup Kit (50 µg, NEB #2040) and eluted with nuclease-free water using the elution volumes indicated. The percent recovery of RNA was calculated from the resulting A260, as measured using a Trinean DropSense™ 16. Approximately 80% of RNA can be efficiently recovered in as little as 20 µl.
Figure 3: The Monarch Spin RNA Cleanup Kit (50 µg) produces sgRNA yields consistent with other suppliers' RNA cleanup kits and with lower residual NTP contamination

Six different sgRNA synthesis reactions from the EnGen® sgRNA Synthesis Kit, S. pyogenes (NEB #E3322) were cleaned up using either the Monarch Spin RNA Cleanup Kit (50 µg, NEB #T2040) or another supplier's kit (according to manufacturer’s recommendations) and eluted with 50 µl of nuclease-free water. sgRNA yield was calculated from the resulting A260, as measured using a Trinean Dropsense™ 16. The Monarch kit produced sgRNA yields consistent with other commercially available RNA cleanup kits.

Following cleanup, residual nucleotides (NTPs) were measured by LC-MS and are reported as (percent area NTPs (rATP+rCTP+rGTP+rUTP)/percent area sgRNA). The Monarch Spin RNA Cleanup Kit consistently outperforms other commercially available RNA cleanup kits in the removal of residual NTPs from sgRNA synthesis reactions.
