Version 2 Oligos[edit]
The version 2 oligos have several changes. The main is that they are shorter and use a UMI on the padlock instead of the latch. I will test these oligos and the new protocol. I'm also going to check
Sample Matrix[edit]
Sample | Condition |
Sample 1 (AB) | Normal |
Sample 2 (AB) | No Template |
Sample 3 (AB) | No C probes |
Sample 4 (AB) | No phosphate activation |
Protocol-Phase 1[edit]
- Phosphorylation-MirrorC Probe B (PCCB-02)
- Set up reaction according to table
- Incubate at 37C for 30 min
- Heat kill enzyme with 15 minutes at 65C
- Template-Bead Binding
- Suspend 2 uL (8 ug) beads per sample in 100 uL wash buffer
- Apply magnet for 30 sec and remove supernatant
- Add 2 uL 10 uM template oligo per sample to bead solution; incubate at RT for 5 min
- Wash beads with 100 uL wash buffer; vortex to suspend; apply magnet and remove supernatant
- C Probe Hybridization
- Combine following into a 0.2 mL tube
- Heat C probes to 90C for 5 min; Chill probes on ice to quench
- Add 5 uL probe mixture to beads
- Incubate at 40C for 1 hour with agitation; start part 4 after incubation begins
- Wash beads with 100 uL wash buffer; apply magnet and remove supernatant
- Repeat wash step above
- Add 100 uL cold Low Salt Buffer; apply magnet and remove supernatant
- Phosphorylation-Lock oligo
- Set up reaction according to table
- Incubate at 37C for 30 min
- Heat kill enzyme with 15 minutes at 65C
- Lock and Latch Hybridization/Ligation
- Set up the following master mix; Note: for sample 4 add un-phosphorylated Lock0201
- Add 19 uL probe mix to each sample; for sample 3 don't add activated lock, add normal lock0201
- Incubate at 65C for 5 min
- Lower temperature to 40C; incubate 20 minutes
- Lower the temperature to 20C; wait 30 seconds then take off incubator
- Add 1 uL T4 Ligase to each reaction
- Incubate at RT for 30 min
- Heat kill enzyme by incubating at 65C for 10 minutes
- Wash twice with 100 uL wash buffer
- Padlock Hybridization
- Make 2 of the following master mix
- 8.2 uL 10 uM padlock0401 or Padlock0401A
- 8.2 uL Amp Ligase 10X reaction buffer
- 65.6 uL nfH2O
- Resuspend sample in 20 uL padlock buffer; incubate A samples with Padlock0401 and B samples with Padlock0401A
- Incubate at 37C for 30 minutes
- Circularization
- Prepare 8.5X uL Phusion mix
- Add 20 uL phusion mix to 20 uL reaction
- Incubate at 40C for 4 hours
