Dystrophin Probes (Started 7/18/2014)[edit]

Back to Calendar

Dye Labeling[edit]

  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[edit]

Sample ng/uL ssDNA pmol/uL dye pmol/uL ssDNA dye/probe bp:dye ratio
Dystrophin-488 23.3 3.9 3.5 1.1 18
Dystrophin-546 25.2 5.5 3.8 1.4 14

Good labeling results. Proceeding to FISH.
