Price From: $80.00



  • More potent than competing human placental RNase inhibitors
  • RNase-free
  • Effective over broad pH range from pH 5.5 to 8.5
  • Active over temperature range from 37°C to 70°C
  • RNase Inhibitor does not interfere with SP6, T7, or T3 RNA polymerase, AMV or M-MLV reverse transcriptase or Taq DNA polymerase
  • RNase Inhibitor increases the time RNA can be safely stored

Unit Definition

One unit is the amount of ribonuclease inhibitor required to inhibit the activity of 5 ng of Ribonuclease A at 25°C (by 50%)
Ribonuclease inhibitor activity is determined by the inhibition of RNase A hydrolysis of cyclic 2',3'-cytdine monophosphate in a spectrophotometer recording assay

Storage Buffer

20 mM Hepes-KOH (pH 7.5)
100 mM KCl
0.1 mM EDTA
50% (v/v) glycerol

Assay Conditions

0.1 M Tris-acetate (pH 6.5 at 22°C)
1 mM cyclic 2', 3'-cytidine monophosphate
Reaction volume of 1 ml

Quality Control

All preparations are tested for contaminating endonuclease and exonuclease and nonspecific RNase and single- and double-stranded DNase activites

Storage Contitions

Store at -20°C
