    Avoiding RNase Contamination
Bacteriophage T3 RNA Polymerase is a DNA-dependent RNA polymerase that is highly specific for the T3 phage promoters. The 99 KD enzyme catalyzes in vitro RNA synthesis from a cloned DNA sequence under the T3 promoters. RNA produced using the T3 RNA Polymerase is suitable for many applications in research and biotechnology.
Product Source
Isolated from E. coli carrying a plasmid which contains T3 gene I.

Notes
  • For radio labeled high specific activity RNAprobes, the concentration of the radioactivenucleotide should be limited to 6 μM.

  • To protect RNA against ribonuclease, RNaseinhibitor (NEB #M0314 or #M0307) should beadded to a final concentration of 1 U/μl.

  • T3 RNA Polymerase is extremely sensitive to saltinhibition. The overall salt concentration shouldnot exceed 50 mM.
