Agi26k0gap Probe Production
- Reference: Matt:LabNotes/2013-5-10
- Use 20nM aliquot of Agilent oligos in tube labeled "FISHYB V1 probes 5/07/13"
Probe Expansion PCR
- Expansion PCR in 200ul total: 2 tubes of 100ul for 0bp gap probes with AP1V6 primers
' | 0 gap probes (ul) |
Agi26k (20nM) | 10 |
2x Kapa SYBG qPCR MM | 100 |
100uM pAP1V6U | 0.8 |
100uM AP2V6 | 0.8 |
H2O | 88.4 |
Total | 200 |
- Mixed thoroughly and then split into two tubes
94C 2min -> (94C 30sec -> 54C 45sec -> 72C 45sec) x 12 -> 72C 3min -> 15C hold

- Purified with 2 Qiagen columns
- Eluted with 40ul each tube and combined into two tubes (80ul total)
- Nanodrop: 32.2 ng/ul -> 32.2ng/ul / (228bp*660Da/bp) = 214nM
- Dilute 2.34ul in 47.66ul H2O
- Final volumes:
- 75ul of 214nM
- 50ul of 10nM
Production PCR
- Make Master Mix for 46 well (6 strips)
- 0 gap first round amplicon -> V6 primers
Components | 1x rxn (ul) | 50x rxn (ul) |
