- 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 a 0.2 mL tube
- 4 uL each PCCA-03 and PCCB-03 (10 uM each)
- 12 uL wash buffer
- 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
- Wash beads with 100 uL wash buffer; apply magnet and remove supernatant
- Repeat wash step above
- Repeat wash step above

Results-CANTC and Efficiency[edit]
Take this with the Friday results

File:20170313-BoltTest-NoLigase-Efficiencies.png
The above graph (and Friday's, which is just this graph without the Sample-TR2 and No Ligase samples) had potentially wrong calculations for efficiency, since they only calculated the amount in the qPCR reaction (2 uL), which is a small fraction of the amount eluted (50 uL).
