Dye coupling

  • Noi did the amplification and prepared single-stranded probes:Noi's lab note.
  • 1mL of nuclease free water was added to the Labeling Buffer tube containing sodium bicarbonate. The tube was placed on the Eppendorf thermal shaker at 37C for ~20 min.
  • Each vial of dye was resuspended in 2ul DMSO.
  • I took 2.5ul of DNA, add 1.5ul of Labeling buffer, then 1ul of dyes. I wasn't able to pipette the exact volume of the dyes due to inexperience and pipetting error.
