  • Follow the Quant-it protocol for DNA (and RNA) quantification.
  • Make up standard measurements along with your samples.
  • If unsure of your scale (if you have a lot or a little) then do 2 concentrations of your sample to check, one at 1:10 other at 1:100
  • add 1ul DNA to 9ul TE (then take 1ul of this and add 200ul)
  • Do 2 of TE or whatever you are resuspending in to subtract this background from your results.
  • set up the plate reader and computer.
  • Add the fluorescent reagent (make up enough: 100 assays = 20 ml HS buffer) - 200ul added to each plate, make sure you have enough and careful when pipetting, keep track of which hole you want to add it to.
  • read the plate
