DNSA reagent base

DNSA reagent



DNSA reagent is used for the colorimetric assay of reducing sugars. Thus it can be used to measure the activity of a wide range of enzymes such as amylase, invertase, cellulase, lactase etc that produce reducing sugars as products of their action.



Detailed Description

Although widely known in schools across the world, DNSA reagent is seldom used in UK schools. Suitable for A Level and equivalent courses that require quantitative measurement of enzyme activity, and the use of a colorimeter.

Note: You will need to add sodium hydroxide to this reagent before it can be used. When made up it will produce 100 mL of the reagent. (Each colorimetric test requires 0.3 mL of this reagent.)
