Beta-glucosidase was purified from a crude cellulase preparation from Aspergillus niger by affinity chromatography on a methacrylamide-N-methylene-bis-methacrylamide copolymer bearing cellobiamine. The purified enzyme was a dimer with an isoelectric point of 4.0. The molecular mass of the enzyme was estimated

In this study, citric acid (CA) esterified canna starch was firstly synthesized with the aid of vacuum, microwave and infrared radiation treatment. The changes in structural, physicochemical properties and in vitro digestibility of the modified starch were then investigated. The

Questions

  1. What buffer should I reconstitute this enzyme for preparing a stock solution? Or does cold deionized water work? Either way, once resuspended, at what temperature should it be stored? Thank you!
