Dye Labeling

  1. Warm DMSO and bicarbonate labeling buffer and nuclease free water to room temperature
  2. Add 5 uL DNA and 3 uL of sodium bicarbonate buffer
  3. Denature samples for 5 minutes at 95C, then snap cool using ice box
  4. Dissolve 1 vial of reactive dye in 2 uL solvent; vortex ≥10 seconds
    1. dye cannot be saved for later use. Use immediately!
  5. Add 2 uL dye to sample
  6. Incubate in the dark for 1 hour
  7. Add 5 uL 3M NaOAc and 40 uL nfH20 to sample
  8. Recommend column purification after incubation

Labeling Results

FISH Hybridization

  1. Allow stored samples to warm to room temperature
  2. Incubate in 2X SSCT +50% (v/v) formamide for 2.5 minutes at 92 C in pre-warmed media
  3. Incubate in 2X SSCT + 50% formamide at 60C for 20 minutes
  4. Remove samples and allow to cool to room temperature
  5. Add 25 uL hybridization cocktail to center
  6. Add 22x22 #1.5 coverslip; seal with rubber cement
  7. Allow the rubber cement to air-dry for 5 minutes at room temperature
  8. Denature for 2.5 minutes at 92C; keep humid
  9. Transfer slides to a humidified chamber and hybridize overnight at 42C
