Ng/Ul Dilution Formula

The following formula is used to calculate the final concentration after dilution.

C2 = C1 * (V1 / V2)

Formula source:  California State Water Resources Control Board – “Units & Conversion Factors” (2016)

Variables:

  • C2 is the final concentration (ng/ul)
  • C1 is the initial concentration (ng/ul)
  • V1 is the initial volume (ul)
  • V2 is the final volume (ul)

To calculate the final concentration after dilution, multiply the initial concentration by the initial volume. Then divide the result by the final volume.

What is a Ng/Ul Dilution?

A Ng/Ul dilution refers to the concentration of a particular substance in a solution, measured in nanograms (Ng) per microliter (Ul). This is commonly used in molecular biology and biochemistry to quantify the concentration of DNA, RNA, or protein in a sample. The dilution process involves reducing the concentration of the substance in the solution, often to make it suitable for a particular experiment or procedure.

How to Calculate Ng/Ul Dilution?

The following steps outline how to calculate the Ng/Ul Dilution using the formula: C2 = C1 * (V1 / V2).


  1. First, determine the initial concentration (C1) in ng/ul.
  2. Next, determine the initial volume (V1) in ul.
  3. Next, determine the final volume (V2) in ul.
  4. Next, insert the values into the formula: C2 = C1 * (V1 / V2).
  5. Finally, calculate the final concentration (C2) in ng/ul.
  6. After calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Initial concentration (C1) = 10 ng/ul

Initial volume (V1) = 5 ul

Final volume (V2) = 20 ul
