Phusion Test[edit]
Hemo Klentaq has strand displacement activity, which could be a potential (big) problem for latch-padlock circularization. Therefore, on Chris and Andrew's recommendation I will try a test using Phusion instead of Hemo Klentaq.
Buffers[edit]
KLN Mix
Reagent | Stock | uL added |
Amp Ligase Buffer | 10X | 2 |
dNTPs | 100 uM | 2 |
Hemo Klentaq | NA | 4 |
Amp Ligase | 5 U/uL | 2 |
nfH2O | NA | 10 |
Phusion Buffer
Reagent | Stock Conc | Final Amount | 1x Vol (uL) | MM Vol (4.1x) (uL) |
NAD+ | 5 mM | 40 nmol | 8 | 32.8 |
dNTP | 1 mM | 600 pmol | 0.6 | 2.46 |

Protocol[edit]
- C-Probe Hybridization
- Measure cell concentrations in cell counter
- Human - 3.05E5 cells/mL; Mouse - 9.75E5 cells/mL (from 7-25-2016)
- Add cells to a new tube such that there are 30000 cells present per sample
- Human- 350 uL (3 samples) uL; Mouse- 30 uL
- 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 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 Padlock0001-68
- 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 pellet in 100 uL LPH buffer with 100 nM Latch0001
- For sample 3, use 10 uL 100 uM Latch0001 (10 uM final concentration)
- Incubate for 30 min at 37C
- Wash twice with 200 uL wash buffer by pelleting cells at 600xg for 3 min
- Incubate cells for 20 min at 40C in 200 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
- 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 (XX hours)
- Continued tomorrow
