- 37C 30min -> 65C 20min -> Qiaquick column purification (also combine the samples used for DpnII digestion trial.
- Measure concentration by Nanodrop and calculate yield

Total yields of DpnII digested DNA are between ~7ug-12ug. I will set up exonuclease digestion in volume 100ul with 100U of lambda exonuclease

Lambda exonuclease digestion reaction set up

Probe IDs Conc. (ng/ul) DpnII digested DNA (ul) 10X Lambda exo buffer Lambda exo (10U/ul)

- 37C 1h -> 75C 10min -> EtOH precipitate
- I took 0.5ul of digested DNA before precipitation and run check in 6% TBE-urea gel

U=undigested DNA 
1,2,3, and 4 = oligo set #
Anyway, PAGE doesn't tell if exonuclease completely cleave or not.
- I precipitated DpnII/Exo oligos because in the following step of probe labeling with ARES™ DNA Labeling Kits (Invitrogen) it requires approx.1-5ug of DNA in limited volume 5ul. 
- From total 100ul Exo digestion reaction I added more H2O 200 ul (total volume 300ul), 1ul Glycoblue, 30ul 3M NaoAc pH5.5 and 900ul 100% EtOH.
-80C O/N
- Resuspend with 7ul H2O
  
PAGE quantification in 6% TBU gel
Dilute 100x (1ul in total 100ul) of purified ssDNA --> load 3ul --> Actual volume in each well = 0.03ul
