For the assay of endo-cellulase. Containing AZCL-HE-Cellulose. Recommended substrate for the assay of endo-cellulase.
Please note the video above shows the protocol for assay of endo-xylanase using xylazyme tablets. The procedure for the assay of endo-Cellulase using Cellazyme AF Tablets is equivalent to this.

New chromogenic substrates have been developed for the quantitative assay of alpha-amylase and (1→4)-β-D-glucanase. These were prepared by chemically modifying amylose or cellulose before dyeing, to increase solubility. After dyeing, the substrates were either soluble or could be readily dispersed to form fine, gelatinous suspensions. Assays based on the use of these substrates are sensitive and highly specific for either alpha-amylase or (1→4)-β-D-glucanase. The method of preparation can also be applied to obtain substrates for other endo-hydrolases.Hide Abstract
