α-L-鼠李糖苷酶（α-L-rhamnosidase，EC 3.2.1.40）是一种能够水解日常饮食中常见黄酮苷类化合物的水解酶，广泛分布于自然界细菌和真菌等生物中，具有广泛的工业应用前景。本试剂盒采用对-硝基酚-α-鼠李糖苷（PNPR） 为底物，酶促水解生成黄色产物对-硝基苯酚（PNP），该产物在405 nm处具有特征吸收峰。通过动力学模式连续监测单位时间内OD₄₀₅的初始线性增幅（ΔOD₄₀₅/min） ，即可精准计算样品中α-L-鼠李糖苷酶的活性大小。
α-L-Rhamnosidase (EC 3.2.1.40) is a hydrolytic enzyme capable of hydrolyzing flavonoid glycosides commonly found in the daily diet. It is widely distributed in organisms such as bacteria and fungi in nature and holds broad prospects for industrial applications. This kit employs p-nitrophenyl-α-L-rhamnopyranoside (PNPR) as the substrate, which is enzymatically hydrolyzed to release the yellow product p-nitrophenol (PNP). PNP exhibits a characteristic absorbance peak at 405 nm. By continuously monitoring the initial linear increase in OD₄₀₅ per unit time (ΔOD₄₀₅/min) in kinetic mode, the α-L-rhamnosidase activity in the sample can be precisely calculated.
