BA8 Section DARTFISH with Fiducial Beads
- Try again: Matt:LabNotes/2015-8-3
- with fresh PFA
- Practice DARTFISH on BA8 tissue sections
- Use FluoSpheres Amine-Modified Microspheres 0.2um (505/515) as fiducial markers
DARTFISH on BA8
- Prepare plastic culture dish with hole, tweezers, large plastic dish, and 50C hot plate
- EtOH sterilize and UV
- Made 40ml 4% PFA
- 10ml 16% PFA from ampule + 4ml 10X PBS + 26ml nuclease-free H2O
- Take out BA8 section from -80C and incubate on 50C hot plate for 3min
- Submerge section in 5ml 4% PFA in 6 well culture plate for 15min at 37C
- Wash with 2X SSPE by submerging in 2 clean wells of culture plate with 5ml SSPE
- Aspirate any liquid and attach glass to bottom of culture dish with double-sided adhesive
- Still had leak so used gap-filling adhesive 200 to seal
- Add 0.25% TX-100 in 2XSSPE and incubate 10min at RT
- 0.25% TX-100 in 2XSSPE tube had crack in cap so not completely sealed
- Wash with nuclease-free H2O three times
- Add 0.01% Pepsin in 0.1N HCl and incubate for 5min at 37C
- 2ul 1%Pepsin + 10ul 2N HCl + 188ul H2O
- Wash with nuclease-free PBS three times
- Can already see tissue is degrading
- Prepare Reverse Transcription Mix on ice

- Incubate 10min at 4C and then ~15hr at 37C
- Tissue is slightly degraded but mostly okay
- Wash with 1X PBS once
- Add 300ul BS(PEG)9 (6ul BS(PEG)9 + 294ul 1X PBS) and incubate 1hr at RT
- Wash with 1X PBS twice
- Add Tris pH8.0 and incubate 30min at RT
- Wash with 1X PBS twice
- RNA Removal
- Add RNase Mix (20ul RNase H 10X Buffer + 2ul Riboshredder + 10ul RNase H + 168ul H2O) and incubate 1hr at 37C
- Wash with H2O twice
- Add Ampligase Mix (no suppressor) and incubate ~3hr at 60C as oven slowly decreases to 55C and held for another ~16hr
- Wrapped with parafilm to prevent evaporation
