Perfectly duplexed RNA produced with Thermo Scientific Replicator RNAi Kit can be processed into siRNA, the key component in RNAi-mediated gene-silencing experiments. In the first step of the dsRNA synthesis, T7 DNA-dependent RNA Polymerase transcribes single-stranded RNA copies from the DNA template molecule.
Subsequently, the ssRNA molecules are directly converted to dsRNA by Phi6 RNA-dependent RNA polymerase in the same reaction mixture. One kit contains materials for producing up to 2.5 mg of pure double-stranded RNA in a 2 mL reaction volume. The high yield of double-stranded RNA obtained with the system is due to a unique combination of the complementary polymerase activities in carefully optimized reaction conditions.
The suitable DNA template is created by PCR amplification, which is carried out using the Thermo Scientific Phusion High-Fidelity DNA Polymerase, ensuring highest possible fidelity.
