Lesson plan
Phadebas
Phadebas is a synthetic biochemical substrate used for both qualitative and quantitative assessment of the α-amylase enzyme. Its active component is DSM-P, microspheres in which a blue dye has been chemically bound. When the substrate is digested by the amylase enzyme in solution, it releases that blue dye at a rate proportional to the quantity of the enzyme present. It is used in a range of applications from quality control tests for food & beverages to detection of saliva stains in forensic investigations.
