RNAse Inhibitor

RNAse Inhibitor

Recombinant Protein which specifically inhibits Ribonucleases A, B and C (20 U/μL)

Product Overview:

RNase Inhibitor is a recombinant protein which specifically inhibits Ribonucleases A, B and C. The protein inhibits RNases by binding noncovalently in a 1:1 ratio with a potent affinity (ki >10-14 M). RNAse inhibitor protein is purified from E.coli strain harbouring a plasmid with cloned gene coding of mammalian RNase inhibitor.

Unit Definition

1 U of RNAse inhibitor is defined as an amount of enzyme that blocks activity of 5 ng of RNase A in 50%.



The enzyme is stable up to 58°C and DTT concentration ranges ( 0.5–1 mM DTT presence is essential for optimal activity). Inactivation of the enzyme occurs at 65°C. The enzyme is active over a broad pH range (pH 5.5 – 9.0).


Includes for 10,000 U:

– 500 μL RNAse Inhibitor (20 U/μL)
