TaqMan RT

DNA Free

  1. In 26ul of sample, add 3ul of 10X Dnase I buffer and 1ul rDNase I
  2. Incubate at 37°C for 20 min.
  3. Add 3ul DNase Inactivation Reagent
  4. Incubate 2 min at room temp with occasional mixing
  5. Spin at 13,000 rpm for 1.5 min at room temperature.
  6. Then transfer supernatant to a new tube.
