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. Also inhibits angiogenin, a neovascularization promoter which is homologous with RNase A.

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 human placenta. 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.

Other Notes

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

This inhibitor of RNase activity is isolated from human placenta and supplied as a buffered aqueous glycerol solution.

Physical form

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

Unit Definition

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