Motor Neurons DARTFISH CA12kNov14_suppv2
- Picked up second batch iPS derived motor neurons from Yeo Lab (Sebastian)
- Fixed in 4% paraformaldehyde (fresh) at 3:00p 6/16/2015
- RT for 15min
- Permeabilized/store in 70% EtOH at 4C (~72 hours before this DARTFISH experiment)
- Fixed in 4% paraformaldehyde (fresh) at 3:00p 6/16/2015
- Last time forgot to add suppressor oligos
- Use 1000X concentration of suppressor oligos to match in vitro experiment
- e.g. 100nM CA12kNov2014_V4 = 28.5pM per padlock probe, therefore 28.5nM of each suppressor oligo
- Use 1000X concentration of suppressor oligos to match in vitro experiment
DARTFISH with suppv2

- RT primer 100uM - 5ul
- Nonamer
- RNase inhibitor 40U/ul - 2ul
- M-MuLV reverse transcriptase 100U/ul - 10ul
- Add RT mixture and incubate for 10min at 4C
- Transfer sample to 37C overnight (~18hrs)
- Wash with 1X PBS once
- Add 300ul cold BS(PEG)9 (4ul stock BS(PEG)9 + 196ul 1X PBS prepared on ice) to sample and incubate 1hr at RT
- Wash with 1X PBS twice
- Add 200ul 1M Tris (pH 8.0) for 30min at RT
- Wash with 1X PBS twice
- Add RNase Mix (168ul H2O + 20ul RNase H Buffer + 2ul Riboshredder + 10ul RNase H) and incubate 1hr at 37C
- Wash with 2ml H2O twice
- Prepare Ampligase mixture on ice
- Suppressor Oligos 50nM (labeled supp V4 ALL 5.18.15) - 55ul
- Ampligase Buffer 10X - 10ul
- Padlock Probes 438nM - 25ul
- Heat to 90C first and snap cool on ice block
- Ampligase 5U/ul - 10ul
- Add Ampligase mix to sample and incubate 3hr at 60C then 21hr at 55C (incubator takes a long time to cool from 60C to 55C with door closed)
