Cell Trial 2[edit]
There may have been issues with the previous run, so I'm going to repeat as is.
- C-Probe Hybridization
- Measure cell concentrations in cell counter
- Add cells to a new tube such that there are 100,000 cells present per sample
- Pellet cells via centrifugation at 600g for 3 min
- Wash with 200 uL wash buffer and pellet cells via centrifugation at 600g for 3 min
- Add 100 uL 50% hematoxylin (filtered) and pellet cells via centrifugation at 600g for 3 min
- Wash once with 200 uL wash buffer and pellet cells via centrifugation at 600g for 3 min
- Wash 2 times with 200 uL wash buffer prime and pellet cells via centrifugation at 600g for 3 min
- Pellet cells via centrifugation at 600g for 3 min
- Combine 0.5 uL of each C probe into a 0.2 mL tube with 2 uL nfH2O
- Heat C probes to 90C for 5 min; Chill probes on ice to quench
- Add probes to 100 uL CPH buffer according to sample matrix, 1 uL probe mix per sample
- 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 100 uL LPH buffer with 100 nM Padlock0201-68 and 100 nM Latch0001
- Incubate for 30 min at 37C
- Wash twice with 100 uL wash buffer by pelleting cells at 600xg for 3 min
- Incubate cells for 20 min at 40C in 150 uL stringent wash buffer
- Resuspend with 20 uL 1x Amp Ligase buffer and transfer to a 0.2 mL tube
- Circularization
- Prepare 20 uL KLN mix
- Add 2 uL KLN mix to 20 uL of reaction for sample 1
- Incubate at 55C overnight (XX hours)
- Continued tomorrow
