Padlock Probe Concentration Test using Med Conc (100nM) Fixed Template[edit]
- Previously fixed 1nM template resulted in almost no rolonies
- 96-well plate PGP1f Cells
- Fixed 12/26/13 and RT with 12/30/13
- Using wells C7-C10, F3-F10
- Marked 1 position for each well (adapter clips on bottom&right)
- .maf file saved in 3-31-2014
- Test padlock probe concentrations NegCtrl-0pM, 10pM, 50pM, 100pM, 1nM, 10nM
Fixing Template in cells[edit]
- Pre-heat 100nM MALAT1_Template to 85C
- Add 50ul to each well
- Incubate @RT for 15min
- Aspirate but don't wash
- Add 50ul BS(PEG)9 mix (12ul BS(PEG)9 + 588ul 1X PBS)
- Incubate @RT for 1hr
- Wash with 1X PBS twice
- Add 50ul 1M Tris pH 8.0
- Incubate @ RT for 30min
- Wash with 1X PBS twice

Secondary RCA[edit]
- Aspirate but don't wash
- Pre-annealing the FISSEQ_ppRCA primer for the rolling circle amplification reaction.
- 3ul of RCA primer(200 uM, GATATCGGGAAGCTGA*A*G) in 597ul of 2xSSC/30% formamide
- Preheat primer at 60C (Tm = 55C when not in 30% formamide)
- Add 50ul and incubate at 45C for 15min.
- Aspirate, and wash using 2x SSC twice
- Aspirate, and wash using 0.1x SSC twice
- Prepare the rolling circle amplification reaction mixtures on ice.
- 513 ul ddH2O,
- 60 ul 10x Phi29 buffer,
- 6 ul 25 mM dNTP,
- 12 ul 2 mM aminoallyl dUTP
- 9 ul Phi29 DNA polymerase (Epicentre, low concentration)
- 600ul Total Volume
- Add 50ul each well and incubate 20hrs at 30C.
- Wash 1X PBS once
- Add 50ul BS(PEG)9 mix to each well and incubate @RT for 1hr
- Wash 1X PBS twice
- Add 50ul 1M Tris pH 8.0 @RT for 30min
- Wash 1X PBS twice
Detection[edit]
- Made 650ul of 1uM dcProbe2-Cy3 (643.5ul 2XSSC & 30%formmaide + 6.5ul 100uM dcProbe2-Cy3)
- Extra volume since some always evaporates when heated
- Pre-heated @75C for 5 min and then added 50ul to each well
- Let sit @RT for 5 min
- Washed twice with 2X SSC
- Saved in 4-2-2014
