Application

Suitable for use in in vitro inhibition of ribonucleases cDNA synthesis RT-PCR in vitro transcription and translation

Useful for in vitro inhibition of ribonucleases, including procedures like cDNA synthesis, RT-PCR, and in vitro transcription and translation.

Biochem/physiol Actions

Inhibits RNase by forming a tight, non-covalent 1:1 complex.

Components

Ribonuclease Inhibitor is provided as a solution in 20 mM HEPES-KOH( pH 7.6), 50 mM KCl, 8 mM DTT and 50% glycerol.

General description

Ribonuclease inhibitor works to inhibit RNase activity by forming a tight, non-covalent 1:1 complex. It is derived from E. coli that express portions of the human placental ribonuclease inhibitor. It inhibits RNases A, B, and C. It will not inhibit RNases H, 1, T1, S1 Nuclease, SP6, T7 RNA Polymerase, T3 RNA Polymerase, AMV Reverse Transcriptase, M-MLV Reverse Transcriptase, or Taq Polymerase. The inhibitor can be removed by phenol extraction or by heating to 65°C for 10 minutes.

Physical form

Solution in 20 mM HEPES-KOH, pH 7.6, 50 mM KCl, 8 mM DTT and 50% glycerol.

Unit Definition

One unit will reduce the activity of 5 ng of ribonuclease A by 50% in a cytidine 2′:3′-cyclic monophosphate system.
