iNGN Bipolar Neurons RNA FISH
- First Try
- Second Try
- Probe dye coupling
- Third Try with cooled CCD camera
- Finally saw some signal using CUX2-Alexa488 48 probes with Sebastian's motor neurons
- Camera did not have DAPI filters so did not use DAPI
- Only used one probe set per sample
- Samples are iNGN Bipolar Neuron's from Alex at Harvard
- Fixed 6/30/2015 and stored in 70% EtOH at 4C for ~9days before RNA FISH
- RNA-Seq FPKM data
- RNA FISH 48 Probes available
- CUX2, SLC6A1, ADARB2, SATB2, KIT, SNAP25
- ADARB2 not in DARTFISH CA12kNov2014_V4
- CUX2, SLC6A1, ADARB2, SATB2, KIT, SNAP25
- SNAP25 has highest FPKM value
- CUX2 is low-medium expression but use as positive control because it was the only one that worked previously
- One sample exact same as last time CUX2-Alexa488 with no DAPI
- One sample with odd CUX2-Alexa488 and even CUX2-Alexa594 to check specificity (should colocalize or else non-specific binding)
- One sample with CUX2-Alexa488 and SNAP25-Alexa 594
