A: The compositions of the buffers are proprietary. We can, however, share the following: Monarch Buffer BX....................Guanidine-based binding buffer Monarch Buffer WX.......................Ethanol-based wash buffer Q: What factors affect my (A260\/A230) when using the Monarch Spin RNA Cleanup Kits? A: Guanidine and ethanol, both introduced during the prep, can reduce the A260\/A230 ratio. Following the protocol, especially the wash steps, will ensure these components are removed. Q: Can I purchase Monarch® buffers and columns separately? A: Monarch spin columns and several Monarch buffers and reagents are also offered separately. Q: Can extraction of RNA with the Monarch kits be automated? A: Yes. NEB has successfully automated the extraction of total RNA (including viral RNA) from saliva samples on the KingFisher™ Flex automation platforms using the workflows for both the Monarch Total RNA Miniprep Kit (NEB #T2010) and the Monarch RNA Cleanup Kit (NEB #T2040), with some protocol modifications. When automated on the KingFisher Flex platform, spin columns are not utilized; instead, magnetic beads (e.g. Dynabeads® MyOne™ Silane magnetic beads) are required. For the purpose of viral RNA extraction, when using the Monarch RNA Cleanup Kit workflow, an added step using Monarch DNA\/RNA Protection Reagent (NEB #T2011), sold separately, is required.

A: Yes. Although originally developed for RNA cleanup applications, these kits can also be used for RNA extraction from cells, saliva, and swab samples. When used for viral extraction, the Monarch DNA\/RNA Protection Reagent (sold separately, NEB #T2011) must be used for viral inactivation.

Are these buffers the same formulation as before? A: Yes NEB is standardizing Monarch buffer naming nomenclature. The buffer names are changing, but the buffer formulations are the same. The Monarch® RNA Cleanup Binding Buffer is now named Monarch® Buffer BX. The Monarch® RNA Cleanup Wash Buffer is now named Monarch® Buffer WX.
