- 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 3 concentrations of your sample to check, one at 100% concentration, one at 1:10 other at 1:100
- add 1ul DNA to 9ul TE to make 1:10, then take a ul of this and add 99ul TE to it to make 1:100
- 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
