Thermostable RNase H has an optimal activity above 65°C and can be used up to 95°C. The enzyme degrades RNA in a DNA:RNA hybrid, maximizing sensitivity and selectivity without affecting DNA or unhybridized RNA.


  • High hybridization stringency
  • Specific hydrolysis of RNA in a DNA:RNA hybrid
  • Diagnostic assay of DNA sequences by isothermal probe amplification
  • Mapping of mRNA structures

A recombinant protein purified from E. coli, cloned the gene encoding the Thermus thermophilus RNase H

Unit Definition:
One unit of the enzyme results in the acid-solubilization of 1 nmol of polyadenylic acid in the presence of an equimolar concentration of polythymidylic acid in 20 minutes at 45°C in 50 mM Tris-HCl(pH 7.5), 100 mM NaCl, and 10 mM MgCl2. Note: The unit assay is performed at 45°C because this is optimal for the Tm of poly(dT):poly(A). The optimal temperature for many applications may be considerably higher.

10x RNAse H Buffer:
500 mM Tris-HCl
