The Monarch 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 ensures 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 RNA Cleanup kits are also available for 50 µg (NEB #T2040) and 500 µg (NEB #T2050) binding capacities. Columns and buffers are also available separately for convenience.

Figure 2: The Monarch RNA Cleanup Kit enables efficient recovery of RNA in as little as 6 µl
rRNA (10 µg of 16S and 23S Ribosomal Standard from E. coli, Sigma) was purified using the Monarch RNA Cleanup Kit (10 µg, NEB #2030) 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. ~80% of RNA can be efficiently recovered in as little as 6 µl. Figure 3: The Monarch RNA Cleanup Kit enables efficient recovery of <20 ng of RNA in as little as 6 µl
A 2-fold dilution series (from 1000 to 15.6 ng) of rRNA (16S and 23S Ribosomal Standard from E.coli, Sigma) was purified using the Monarch RNA Cleanup Kit (10 µg, NEB #1030) and eluted in 6 µl of nuclease-free water. The percent recovery of RNA was calculated from the resulting A260, measured using a Trinean DropSense 16. Even low RNA inputs (<20 ng) are efficiently cleaned up and recovered (>80%) in as little as 6 µl. Figure 4: The Monarch RNA Cleanup Kit (10 µg) offers efficient recovery of sample volume
The Monarch RNA Cleanup Columns (10 µg, NEB #T2037) ensure zero buffer retention and no carryover of contaminants, enabling sample elution in volumes as low as 6 µl. Moreover, ~90% (~5.4 µl) of the minimal elution volume is recovered from the Monarch RNA Cleanup Columns, compared to other competitor kits.
