    Avoiding RNase Contamination

Bacteriophage SP6 RNA Polymerase is a DNA-dependent RNA polymerase that is highly specific for the SP6 phage promoter. The 98.5 KD polymerase catalyzes in vitro RNA synthesis from a cloned DNA template under the SP6 promoter. RNA synthesized using the SP6 RNA Polymerase is suitable for many applications in research and biotechnology.

Reaction Conditions:
1X RNAPol Reaction Buffer, supplemented with 0.5 mM each ATP, UTP, GTP, CTP and DNA template containing the SP6 RNA Polymerase promoter. Incubate at 37°C. 

Product Source
An E. coli strain that carries the cloned gene for SP6 RNA Polymerase from Salmonella typhimurium LT2Z.

Notes
  • For radio labeled high specific activity RNA probes, the concentration of the radioactive nucleotide should be limited to 6 μM. 
  • To protect RNA against ribonuclease, RNase inhibitor (NEB #M0314 or #M0307) should be added to a final concentration of 1 U/μl. 
  • SP6 RNA Polymerase is extremely sensitive to salt inhibition. The overall salt concentration should not exceed 50 mM. 
  • SP6 RNA Polymerase is slightly more active at 40°C than at 37°C. Incubation at 40°C may be considered for RNA transcript containing strong secondary structures.
