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.

The source of this product can be found on the lot specific Certificate of Origin. This product is from species ASPERGILLUS NIGER. Please access a Certificate of Origin in the DOCUMENTATION section under 'Certificate of Origin':
https://www.sigmaaldrich.com/product/sigma/a7095#product-documentationAmyloglucosidase from A. niger exists as two isoforms with molecular weights of 69,810 kDa and 89,130 kDa, as determined by SDS-PAGE. See: Starch, 34, 346 (1982). The units/mL is determined per batch as reported in Certificate of Analysis. The purity is not part of product specification and is not determined.
