Protocol
- Latch and Padlock Hybridization
- Suspend 1 uL (4 ug) beads per sample in 100 uL wash buffer
- Apply magnet for 30 sec and remove supernatant
- Add 2 uL oligo per sample to bead solution; incubate at RT for 5 min
- Apply magnet for 30 sec and remove supernatant
- Wash beads with 100 uL wash buffer; vortex to suspend; apply magnet and remove supernatant
- Add 2 uL correct latch (10 uM stock) and 2 uL 10 uM Padlock0001-68 to each sample to a fresh 0.2 mL tube
- Dissolve target in 50 uL wash buffer and heat at 65C for 5 minutes
- Chill on ice for 3 minutes
- Add sample to prepared strep beads; vortex to suspend
- Incubate for 30 min at 37C with intermittent mixing
- Apply magnet and remove supernatant
- Add 100 uL wash buffer and vortex to suspend beads; apply magnet and remove supernatant
- Repeat wash step above
- Add 100 uL cold Low Salt Buffer and vortex to suspend; apply magnet and remove supernatant
- Resuspend with 20 uL 1x Amp Ligase buffer
- Circularization
- Prepare 20 uL KLN mix
- Prepare 4.1x master mix of Phusion mix
- Add 20 uL Phusion mix to 20 uL of reaction for samples 2-5
- Add 2 uL KLN mix to 20 uL of reaction for sample 1
- Incubate at 55C overnight; continued tomorrow
