FCS Sample Prep

  • Green fluorescent beads
    • 10000x diluted
    • To be run 3x, 90s
  • Oligo D
    • 150, 125, 100pM
    • To be run 3x, 300s (increase to 500s if noisey)
  • DNA/MB
    • 100/80, 75/60, 50/40pM
    • Heated at ~70C for 25 min, cooled for at least 20 min
    • To be run 3x, 500s (increase to 700s if noisey)

FCS Data

FCS data 2013 0702 beads curve.PNG<br.> Beads used to align laser; three samples run at 90s each, average values used. Curve turned out as expected.<br.> FCS data 2013 0702 Oligo D comparison.PNG<br.> Oligo D: three samples run at each concentration, 500s each, average values used. Y-intercepts increase as concentration decreases, as expected.<br.> FCS data 2013 0702 DNA-MB comparison.PNG<br.> DNA/MB: three samples run at each concentration, 500s each, average values used. Y-intercepts increase as concentration decreases until 50pM. DNA in excess rather than MB to ensure binding.<br.> FCS data 2013 0702 calibration.PNG<br.> Calibration graphs for Oligo D and DNA/MB samples. Oligo D trend turned out as expected; DNA/MB trend dropped at 50pM concentration. DNA/MB samples will be remade and run again tomorrow. <br.>
