Mirror Probe Test
This is a continuation of the failed experiment from Friday with a corrected version of the template.
Sample Matrix
Sample | Condition |
Sample 1 (AB) | Normal |
Sample 2 (AB) | No Template |
Sample 3 (AB) | No C probe |
Protocol
- 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 1 uL of each C probe (10 uM stock) and 3 uL bead wash buffer 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 3 after incubation begins
- Latch and Padlock Hybridization
- Add following to a fresh 0.2 mL tube
- 12.2 uL Latch0001, 10 uM stock
- 12.2 uL Padlock0201, 10 uM stock
- 12.2 uL Amp10X buffer
- 85.4 uL nfH2O
- Add 20 uL probe mix to each sample; incubate 20C for 4 min
- Incubate at 95C for 5 min
- Incubate at 60C for 1.5 hours
- Circularization
- Prepare 7X uL Phusion mix
- Add 20 uL Phusion mix to 20 uL of reaction
- Incubate at 60C for 2 hours
Continued tomorrow
