Stage 2 Test
The purpose of this experiment is to test the latch and padlock binding, termed stage 2 (at the moment). This is based on the success of the VIM binding for both C-Probes and antibodies.
Protocol
Sample Matrix
Sample | VIM-C1 (1 uL) | VIM-C2 (1 uL) |
Sample 1 | X | X |
Sample 2 |
- C-Probe Hybridization
- Split cells into 2 samples (1 mL methanol each)
- Pellet cells via centrifugation at 600g for 3 min
- Put 1 uL C1 Probe and 1 uL C2 probe into a 0.2 mL tube
- Heat C probes to 90C for 5 min; Chill probes on ice to quench
- Add probes to CP buffer for final concentration of 100 nM (Add 1 uL probe mixture to 0.5mL hybridization buffer)
- Incubate probes at 40C for 1 hour with vigorous agitation
- Wash three times with 200 uL wash buffer and pelleting at 600xg for 3 min
- Incubate cells for 20 min at 40C in 200 uL stringent wash buffer
- Latch and Padlock Hybridization
- Pellet at 600xg for 3 min and remove supernatant
- Resuspend pellet in 50 uL hybridization buffer with 100 nM insert/backbone oligos for 30 min at 37C
- Wash twice
- Wash by pelleting cells at 600xg for 3 min
- Circularization
- Prepare KLN mix with:
- 20% v/v HemoKlentaq
- 0.5 U/μL Ampligase
- 100 μM of dNTP mix
- 1x Ampligase Buffer
- Add 2 uL KLN mix to 20 uL of reaction
- Incubate at 55C overnight for 4-20 hours
- Continued tomorrow
- C-Probe (CP) Buffer
- 100 nM insert/backbone oligos
- 1X SSC
- 40 U/mL RNasin
- PBS
- Wash Buffer
- PBS
- 0.1% Tween
- 4 U/mL RNasin
