EtOH Precipitation
- 6 15-ml tubes (with 8.5 wells of PCR product each) for 0gap
- 850ul PCR product
- 2000ul 100% EtOH
- 2.7ul GlycoBlue
- 85ul 3M NaOAc pH 5.2-5.5
- Vortexed and put in -80C for overnight
- Centrifuged at 3000rpm at 4C for 30min
- Discarded supernatant and added 800ul of cold 80% EtOH
- Transferred DNA pellet (with 1ml pipette tip) to 6 1.5mL tubes
- Centrifuged 1.5ml tubes at 15,000rpm for 5 min on table-top centrifuge
- Discarded supernatant and air-dried for 5 min in hood
- Resuspended DNA with 100ul H2O
Qia Column Purification
- Purified 6 tubes of 100ul in 6 columns following Qiagen protocol
- Eluted each column with 40ul and combined all probes into one 1.5ml
- Measured concentration with Nanodrop:
- ~225ul of Agi26k0gap probes: 317.5 ng/ul => 71.4 ug
Lambda Exonuclease Digestion
- Divide into seven pcr tubes of 32ul with total amplicon of ~10ug each
- Seventh tube had 33ul of amplicon
Components | Volume |
Amplicon | 32 |
10X Lambda Exo Buffer | 10 |
Lambda Exonuclease | 10 |
H2O | 48 |
Total | 100 |
- Incubated at 37C for 1hr
- Purified with Zymo ssDNA/RNA columns
- Eluted with 40ul each
- Recombined and measured ssDNA with Nanodrop:
- 89.0ng/ul x 255ul = 22.7ug (63.6% yield)
