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.

  • Application:Biochemical
  • Description:I used this biochemical kit to detect the content of free fatty acids in the liver of rats, and the experimental results could be obtained quickly according to the operation steps in the kit instructions.The formula notes in the specification are detailed, and the calculated results are clear and accurate.The sample took a little longer to process, and overall, the kit was excellent.
