RNAzol® RT RNA Isolation Reagent


RNAzol®RT is the most effective reagent for isolation of total RNA and small RNA from samples of various origins, including human, animal, plant, bacterial and viral origin.

RNAzol®RT separates RNA from other molecules in a single-step based on the interaction of phenol and guanidine with cellular components. No chloroform-induced phase separation is necessary to obtain pure RNA.  It isolates mRNA and microRNA in separate fractions. Alternatively, total RNA containing all classes of RNA in a single fraction can be isolated. In addition, the patented reagent allows for the sequential isolation of RNA and DNA.


Higher yield and quality

  • Isolate pure and undegraded RNA that is ready for RT-PCR without DNase treatment
  • Provides higher yield and quality of isolated RNA than previous reagents

Easy isolation of mRNA, microRNA or total RNA

  • Isolate mRNA and microRNA in separate fractions
  • Isolate total RNA in one fraction

Fast and convenient

  • The isolation procedure can be completed in less than one hour
  • No chloroform-induced phase separation is necessary
  • Stable at room temperature for both storage and experimental procedure
