FCS Data: Calibration Curves

FCS data 2013 0701 OD, MB-DNA calibrations.PNG<br.> Green fluorescent beads were run for 90s to align laser.<br.> Oligo D samples were run for 300s.<br.> MB-DNA samples were heated to ~70C for 25 min, cooled for 20 min, and run at 500s.<br.>

Notes

  • Use green fluorescent beads to align laser
  • Calibration curves did not turn out as expected (linear trend)
  • DNA, not MB, should be in excess for DNA-MB samples to ensure all MB is bound
  • Focus on three concentrations, run each sample several times, average curves based on best spectra taken today
    • Oligo D: 150, 125, 100pM run three times at 500s per sample
    • DNA/MB: 100pM DNA/80pM MB, 75/60, 50/40pM run three times at 500s per sample (increase to 700s per sample if spectra are noisey)
