Webb12 aug. 2024 · Example: Make only 300 μL of a 1:1000 dilution, assuming the smallest volume you can pipette is 2 μL. Choose step DFs: With a total dilution factor of 1000, you can do a 1:10 followed by a 1:100 (10 * 100 = 1000) Formula for 1:10 Dilution: Final Volume / Solute Volume = DF. Plug values in: (20 μL) / Solute Volume = 10. WebbFluorescence intensity is an important parameter that can be used to measure the concentration of a target in a fluorescence detection method. The following five factors determine fluorescence intensity: (1) The fluorescence intensity (ϕ em) is proportional to the intensity of excitation light (ϕ ex).(2) The absorption coefficient α of the fluorescent …
