DNS Reductive Sugar Measurement
DNS solution preparation:
- Disolve 2.5g of 3,5-Dinitrosalicylic acid (DNS) to 150ml double distilled water.
- Heat to solution to 45 degree Celsius and add 4g of NaOH. Stir the solution until it is transparent.
- Add 75g of potassium sodium tartrate and add water to 250 ml.
- Keep the solution without light exposure. The solution can be used after 7 days.
Principle:
Under base solution, DNS will turn to brown color while reacting with reductive sugar in high temperature. In the specific temperature range, the color will have linear relationship with the reductive sugar concentration.
Calibration:
- Prepare glucose or xylose water solution to the following concentration: 0, 0.2, 0.4, 0.8, 1.0, 1.2, 1.6, 2 g/L.
- Take 200 ul of sample, add 200 ul of DNS solution.
- Heat the sample at 100 degree Celsius for 10mins.
- Cool down the sample with ice to room temperature.
- Measure the optical density of the sample with 540nm light wavelength.
- Draw the graph of sugar concentration with respect to optical density.
Calibration results:
Measurement:
- Take 200 ul of sample, add 200 ul of DNS solution.
- Heat the sample at 100 degree Celsius for 10mins.
- Cool down the sample with ice to room temperature.
- Measure the optical density of the sample with 540nm light wavelength.
- Get the concentration of reductive sugar from the Calibration graph.
