Description
Ribonuclease Inhibitor RNase-free inhibits the activity of RNase A, B, C by binding them in a noncompetitive mode at a 1:1 ratio. It does not inhibit RNase 1, T1, T2, H, U1, U2, CL3 and other enzymes.

Concentrations 
40u/μl

Features

• Performs under a wide range of reaction conditions.
• Protects RNA from degradation at temperature up to 55˚C.
• Increase the time RNA can be safely stored.

Assay Conditions 
100mM Tris-HCl (pH 7.5), 1.2mM EDTA, 0.1mg/ml BSA, 100ng/ml RNase, 0.1mg/ml E.coli [³H]¯RNA, 50mg/ml yeast RNA and 8mM DTT.

Storage Buffer 
20mM HEPES-KOH (pH7.5), 50mM KCl, 5mM DTT and 50% glycerol.

Thermal Inactivation 
65˚C for 15 minutes

Unit Definition 
1u is defined as the amount of ribonuclease inhibitor that inhibits the activity of 5ng of Ribonuclease A by 50%.

Application

Applied in procedures where RNase contamination constitutes a problem:

- in vitro transcription.

- in vitro translation.

- cDNA synthesis.

- isolation of mammalian cell fractions that contain mRNA-protein complex.

- separation and identification of specific ribonuclease activities.

Quality Control
The absence of endodeoxyribonucleases, exodeoxyribonucleases, phosphatases and ribonucleases confirmed by appropriate quality tests. Functionally tested in RNA and cDNA synthesis.
