RNaseOUT Recombinant Ribonuclease Inhibitor is a potent noncompetitive inhibitor of pancreatic-type ribonucleases such as RNase A and is used to avoid RNA degradation in a variety of applications. It is an acidic protein with a molecular weight of ∼52 kDa that inhibits RNase A, RNase B, and RNase C.

The robust molecular structure of the RNaseOUT™ inhibitor together with a very high binding affinity for pancreatic-type RNases ensures superior protection of RNA from degradation making RNaseOUT™ highly effective and reliable in various molecular biology applications. 

Features

  • Stable under prolonged reaction conditions—effective RNA protection from RNases at:
    • 4°C for at least 96 hours
    • 25°C for at least 96 hours
    • 37°C for 24 hours
    • 50°C for up to 6 hours
  • Oxidation resistant—highly stable and requires low concentrations of DTT to retain RNase inhibiting activity
  • Wide activity temperature range—maintains full activity from 4°C to 55°C
  • Superior quality—stringent quality control and industry leading manufacturing process

Applications

  • In vitro transcription and translation
  • CRISPR guide RNA production
  • RNA purification
  • cDNA synthesis
  • RT-PCR
  • RT-LAMP
  • RNA-seq
  • RNA modification and labeling

Source

Purified by affinity chromatography from E. coli expressing a cloned porcine gene.

Performance and quality testing

  • SDS-PAGE purity
  • Endo-deoxyribonuclease assay

- 10 mM dNTP Mix (Cat. Nos. 18427013, 18427088)
- RNAseOUT Recombinant Ribonuclease Inhibitor (Cat. No. 10777019)
- E. coli RNAse H (Cat. Nos. 18021014, 18021071)

What does RNaseOUT Recombinant RNase Inhibitor do?

The inhibitor acts as a safeguard against degradation of target RNA due to ribonuclease contamination of the RNA preparation.

What is the concentration of RNaseOUT Recombinant Ribonuclease Inhibitor in Units/microL?

RNaseOUT Recombinant Ribonuclease Inhibitor is provided at a concentration of 40 U/µL.

What is the temperature limitation of RNaseOUT Recombinant Ribonuclease Inhibitor (Cat. No. 10777019)?

RNaseOUT Recombinant Ribonuclease Inhibitor (Cat. No. 10777019) unit reaction conditions are defined at 25 degrees C. The upper temperature limit for full functionality is 40 degrees C. The enzyme half-life is decreased as temperatures increase above 40 degrees C. There is some residual activity up to 50-55 degrees C but heating at 65 degrees C will inactivate the enzyme. As RNaseOUT can be used in various applications like cDNA synthesis, RT-PCR, and in vitro transcription, the recommendation is to follow the temperature settings required for the respective method.

I am having trouble performing PCR amplification after DNA isolation with RNAlater-treated samples. Does RNAlater have an impact on downstream PCR applications?

RNAlater should not impact downstream PCR amplification as long as the sample has been properly cleaned before proceeding with DNA isolation, as stated in the RNAlater Stabilization Solution manual (https://assets.thermofisher.com/TFS-Assets/LSG/manuals/7020M.pdf) on page 7.
