      Detection principle

      Under the condition of weak acidity, non-esterified free fatty acids (NEFA) react with nantokite to form copper soap, which has a specific absorption peak at 715nm. The content of NEFA can be calculated by measuring the OD value at 715 nm.

      Dilution of sample

      It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.05-2.0 mmol/L).

      The recommended dilution factor for different samples is as follows (for reference only):

      Sample type

      Dilution factor

       Rat liver tissue homogenate

      1-3

       Rat heart tissue homogenate

      1

               Rat kidney tissue homogenate

      1

       Mouse liver tissue homogenate

      1-3

      Rat serum

      1

      Mouse serum

      1

      Human serum

      1

      Note: The diluent is Reagent 1.
