Invitrogen™ RNaseOUT™ Recombinant Ribonuclease Inhibitor

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
