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.)
