iNGN Bipolar Neurons RNA FISH

  • RNA FISH 48 Probes available
    • CUX2, SLC6A1, ADARB2, SATB2, KIT, SNAP25
      • ADARB2 not in DARTFISH CA12kNov2014_V4
  • 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

Combining CUX2_odd and CUX2_even

  1. Oligos already resuspended in 15 uL nuclase-free H2O (1 mM)
  2. Take 2 uL from each oligo well and combine them in a single 1.5 mL tube (total concentration 1 mM)
    1. Store the remaining oligos at -20C
  3. Add 230 uL nuclase-free, diluting 10:1, for final concentration of 100 uM
    • Technically closer to 5:1 dilution but final result is closer to 10:1 because starting concentration is actually lower...
    • Goal is to get 1ug/ul DNA concentration
  4. Check concentration in nanodrop at 1:1, 5:1, and 10:1 dilutions for accuracy
