General description
Stabilized with glucose.
Amyloglucosidase is a disaccharidase−type alpha-glucosidase, produced by several species of Aspergillus genus. Immobilization of amyloglucosidase is known to increased its stability.

Application
Amyloglucosidase from Aspergillus niger has been used in in vitro digestions. It has also been used in the isolation of insoluble and soluble dietary fibre from quinoa and amaranth.
Biochem/physiol Actions
Amyloglucosidase from Aspergillus niger is capable of hydrolyzing the α-D-(1-4), the α-D-(1-6), and the α-D-(1-3) glucosidic bonds of oligosaccharides.[1] Amyloglucosidase is an extracellular enzyme that converts starch to dextrins and glucose. The enzyme is used in the starch-processing industry for the commercial production of D-glucose from corn syrups.[2]

Can I dilute the amyloglucosidase enzyme (A7095) in distilled/deionized water or should I use any specific buffer for dilution?
1 answer-
Unfortunately, the formulation of this solution is considered proprietary. There is no information regarding further dilutions, however the optimum pH is 4.5. Any aqueous diluent should be in this approximate range. See the table below to review the pH on enzyme activity.
