Product Details
Ribonuclease R (RNase R) is a magnesium-dependent 3′→ 5′ exoribonuclease that digests linear RNAs. RNase R does not digest lariat or circular RNA structures.
Application
Removal of precursor linear RNA after circularisation of RNA
Alternative splicing studies
Gene expression studiesUnit Definition

Performance Data
SDS-PAGE
The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
Bioactivity
Mixing 1ug ssRNA with 0.6-3U RNase R at 37°C, 30min then electrophoresis detection, it was observed that the ssRNA bands became weak or even disappeared.
1 ug circRNA substrate was mixed with 0.5-2 U RNase R at 37 °C, 30min then electrophoresis detected, there was no significant change in circRNA.
