New England Biolabs, Inc. RNase R – 400 units

Supplier: New England Biolabs, Inc. M0100S
Ribonuclease R (RNase R) is a processive 3' to 5' exoribonuclease. RNase R requires a 3' single-stranded RNA substrate that is approximately 10 nucleotides or longer, such as a poly(A) tail, for proper binding. RNase R is unique from other exoribonucleases for its ability to degrade highly structured RNAs without the need for an additional helicase. Circular RNAs and lariat RNAs are enriched after RNase R digestion as these closed RNA structures are resistant to exoribonucleases.
- Highly processive 3' to 5' exoribonuclease
- Digests nearly all linear RNAs with an accessible 3' end, including rRNA and mRNA
- Enriches for circular RNAs and lariat RNAs from total RNA preps
- Inactivated with the addition of excess EDTA
