Agi15k_Feb2017_V4 Probe Production
- Production of Padlock Probes (V4) Matt:LabNotes/2017-2-8
Notes from last time
- Do 12 or 13 cycles Production PCR
- Experiment with 1hr vs 2hr Lambda digestion
- Think of way to maximize USER and DpnII digestion
Production PCR
- 25nM 1st round amplicons
- V4 master mix made in 2 5ml tubes
Components | Volume (1X) | Volume (100X) |
First round amplicon Agi15k_Feb2017_V4 (25nM) | 0.1 | 10 |
2X KAPA SYBG MM | 50 | 5000 |
AP1V4U (100uM) | 0.4 | 40 |
AP2V4 (100uM) | 0.4 | 40 |
H2O | 49 | 4910 |
Total | 100 | 10000 |
Program 98C 1min -> (98C 10sec -> 55C 30sec -> 72C 45sec) x 13 -> 72C 2min -> 15C hold
EtOH Precipitation
- 8 5-ml tubes (with 12 wells of PCR product each) for V4
- 1200ul PCR product
- 3000ul 100% EtOH
- 3ul GlycoBlue
- 120ul 3M NaOAc pH 5.2-5.5
- Vortexed and put in -80C for overnight
- Centrifuged at 3,000rpm at 4C for 30 min
- Discarded supernatant and added 800ul of cold 80% EtOH
- Transferred DNA pellet (with 1ml pipette tip) to 8 1.5mL tubes
- Centrifuged 1.5ml tubes at 14,000rpm for 5 min at 4C
- Discarded supernatant and air-dried for 10 min in hood
- Resuspended DNA with 100ul H2O
Qia Column Purification
- Purified 8 tubes of 100ul in 8 columns following Qiagen protocol
- Eluted each column with 50ul and combined all into one 1.5ml
- Measured concentration with Nanodrop:
~400ul of V4 probes: 244.2 ng/ul => ~97.64 ug
