本试剂盒用于测定木聚糖酶活力。土壤半纤维素酶于酸性环境下将木聚糖降解为还原糖，还原糖在沸水浴中与 DNS 试剂显色，于 540 nm 处测定吸光度。吸光度上升速率与还原糖生成量成正比，以此计算酶活力大小。
This kit is used for the determination of xylanase activity. Soil hemicellulase degrades xylan into reducing sugars under acidic conditions. The reducing sugars react with DNS reagent in a boiling water bath to develop color, and the absorbance is measured at 540 nm. The rate of increase in absorbance is proportional to the amount of reducing sugars generated, from which the enzyme activity is calculated.
