Xylazyme Tablets

High purity dyed and crosslinked Xylazyme (100 mg tablets) for the measurement of enzyme activity, for research, biochemical enzyme assays and in vitro diagnostic analysis.

For the assay of endo-1,4-β-D-xylanase. Containing AZCL-arabinoxylan (wheat). This substrate is the same as Xylazyme AX except for the larger tablet size (i.e. 100 mg cf. 60 mg) and slightly different assay format.
