- Purified each with 1 Qiagen column and eluted with 50ul H2O
- Nanodrop:
- V4: 10.8 ng/ul -> 10.8 ng/ul / (188bp*660Da/bp) = 87nM
- V7: 17.8 ng/ul -> 17.8 ng/ul / (190bp*660Da/bp) = 142nM
- Diluted to 10nM
- V4: 50ul x 87nM = 435ul x 10nM
- Add 385ul H2O
- V7: 50ul x 142nM = 710ul x 10nM
- Add 660ul H2O
- V4: 50ul x 87nM = 435ul x 10nM
