RNasin® Ribonuclease Inhibitor

Recombinant RNasin® Ribonuclease Inhibitor reliably protects your RNA samples from purification to downstream applications

  • Inhibits a broad spectrum of eukaryotic RNases over a wide pH range (5-8)
  • Maintains inhibitory activity over a wide range of temperatures (4-50°C)
  • Compatible with many downstream applications such as cDNA synthesis, RT-qPCR, and in vitro transcription/translation

Water and buffer stocks can be a source of RNase contamination. Several stocks from an RNase-free zone in an academic lab showed RNase activity. Recombinant RNasin® Inhibitor protected all RNA samples from degradation. See Full Experiment

pGEM® Express Control Template was transcribed using the RiboProbe® System—T7 following the instructions in Technical Manual #TM016. All reactions were performed in duplicate. Expected sizes in bases are displayed on the right of the gel image, and marker sizes in kb are listed on the left. The graph was generated by quantitating the bands on the gel and calculating a percent RNA compared to the positive control (polymerase + template). Error bars represent the two separate reactions. The black bars are quantitation of the top bands (2,346 bases) and the grey bars are quantitation of the bottom bands (1,065 bases).

Comparison of RNasin® Ribonuclease Inhibitor and RNaseOUT™ inhibition of RNase A during in vitro transcription.

Kanamycin Control RNA was reverse transcribed and amplified using the Plexor® One-Step qRT-PCR System with the addition of either Recombinant RNasin® Inhibitor or RNaseOUT™ Inhibitor. See Full Experiment

We analyzed samples with varying concentrations of Recombinant RNasin® Ribonuclease Inhibitor before and after six weeks of storage with repeated freeze-thaw cycles. Panel A. Represents samples before storage. Panel B. Represents samples after the six-week period. The gel models demonstrate that the samples show little RNA degradation.
