High purity Amyloglucosidase (Aspergillus niger) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.

For use in Megazyme Total Starch and Dietary Fiber methods. Amyloglucosidase, Fructanase (E-FRMXPD) and Isoamylase (E-ISAMY) are used in the enzyme hydrolysis step of two validated methods for the determination of polydextrose (a low molar mass dietary fiber) in foods: AOAC method 2000.11 and Chinese GB Standard 5009.245-2016.

E-AMGDF-A-100ML specifically to be used with ANKOMTDF Dietary Fiber Analyzer.
