Motor Neurons DARTFISH CA12kNov14_suppv2[edit]
- Received Bipolar Neurons (iNGN) from Alex at Harvard
- Fixed in 4% paraformaldehyde (fresh) 6/30/2015
- RT for 15min
- Permeabilized/store in 70% EtOH at 4C (~24 hours before this DARTFISH experiment)
- Fixed in 4% paraformaldehyde (fresh) 6/30/2015
- Follow protocol from last time
- 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
