Phi6 RNA Replicase is a modified version of the protein P2 from bacteriophage Phi6. This novel RNA-dependent RNA polymerase catalyzes the synthesis of a full-length complementary RNA strand initiating from the 3' terminus of a single-stranded RNA. The polymerase does not require any oligonucleotide primer for the initiation. Due to a unique modification, the Phi6 RNA Replicase displays relatively low template specificity, and it is therefore capable of replicating a great variety of RNA templates as well as denatured DNA that contains a recognition sequence for the Phi6 RNA Replicase at its 3' terminus.


  • Replication of ssRNA to dsRNA form
  • ssDNA replication to RNA/DNA hybrid
  • For producing larger amounts of dsRNA, Replicator RNAi Kit is recommended


  • Phi6 RNA Replicase is supplied with 10X Phi6 RNA Replicase Buffer and 50 mM MnCl2 solution. 1X buffer contains: 50 mM Tris-HCl (pH 8.75 at 21°C), 50 mM NH4Ac.
