Digestion of PGP1F with Rnase I

 PGP1F(35ng/ul) 100ul + 10U/ul Rnase I 2ul -> 37C 30mins -> 70C 20mins.
 IMR90(25ng/ul) 100ul + 10U/ul Rnase I 2ul -> 37C 30mins -> 70C 20min. 
 Purify with Microcon column.
 Yield: 
 IMR90 50ng/ul x 40ul. 260/280=0.96
 PGPF1 57.8ng/ul x 50ul. 260/280=0.96

  • Add 900ul ddH2O, 300ul M-Dilution Buffer and 50ul M-Dissolving Buffer to a tube of CT Conversion Reagent.
  • Add 130ul of CT conversion reagent to samples.
  • 98C 10min -> 64C 150min -> 4c overnight.
  • Add 600ul M-Binding buffer to spin columns.
  • Add the converted samples to the columns, close the gap and mix by inverting several times.
  • Spin at 15,000rpm for 30sec.
  • Add 100ul M-Wash Buffer, spin for 30 sec, discard flow-through.
  • Add 200ul M-Desulphonation Buffer, wait for 20min, spin at 15,000 rpm for 30sec.
  • Add 200ul M-Wash Buffer, spin for 30 sec.
  • Place the columns into 1.5ml tubes, add 10ul M-Elution Buffer. Wait for 1min, spin at 15,000rpm for 30sec.
  • Measure the DNA with Nanodrop:
