Circularization Comparison (T4 Poly/Ligase)
Based on the March 8 experiment I will try the protocol again with a special note for testing against the bolt oligo and paying close attention to circularization.
Protocol
Sample Matrix
Sample | Condition |
Sample 1 (AB) | Normal |
Sample 2 (AB) | No Template |
Sample 3 (AB) | No C probes |
Sample 4 (AB) | Dephosphorylated |
Sample 5 (AB) | Positive Control (C4-C2) |
- Note:Because sample 5 is the finished product (ligated C probes), it will be started at step 5
******
- 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 0.2 mL tubes
- 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 step 3 during this process
- Wash beads with 100 uL wash buffer; apply magnet and remove supernatant
- Repeat wash step above
- Repeat wash step above
******
Reagent | uL per Sample | Exp uL Total (1,2,4) | No C uL Total (3) |
PCCA-03 (10 uM) | 1 | 6 | 0 |
PCCB-03 (10 uM) | 1 | 6 | 0 |
Wash buffer | 3 | 18 | 10 |
Total | 5 | 30 | 10 |
Protocol-Part 2
- Dephosphorylation (Bolt Oligo)
- Mix the following reaction
- 5 uL Bolt0301 (10 uM)
- 2 uL CutSmart Buffer (10X)
- 2 uL rSAP enzyme
- 16 uL nfH2O
- Incubate at 37C for 30 minutes
- Incubate at 65 for 5 minutes
- Lock and Latch Hybridization/Ligation
- Set up the following master mix
- Add 19 uL probe mix to each sample
- Incubate at 55C for 10 minutes
- Incubate at 25C for 10 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 15 min
- Heat kill enzyme by incubating at 65C for 10 minutes
- Padlock Hybridization
- Wash samples one time and resuspend in 30 uL nfH2O
- Bake samples at 95 C and vortex to resuspend
- Note: Here I accidentally added the Phusion mix to the Y samples before adding the enzymes, so this is adjusted to only analyze the Z samples. Y samples will be processed tomorrow.
- Make the following master mixes
- Add 14 (X) or 15 (YZ) uL master mix to appropriate tubes
- Add 5 uL sample according to tables
- Incubate at 50C for 20 minutes
- Circularization
- For phusion samples, make the following master mix
- Follow the workflow in the below diagrams File:CircProtocol-T4Poly.png Continued tomorrow
