Application
蛋白酶K-琼脂糖被用于分离蛋白质和核酸、修饰酶和固定酶。蛋白酶K-琼脂糖已被用于研究家犬的肺炎克雷伯菌（肺炎克雷伯菌）和多房棘球绦虫（Echinococcus multilocularis）感染。
Biochem/physiol Actions
通过将蛋白酶K固定在不溶性基质上，如琼脂糖，可将其用于更多应用中。琼脂糖在大多数系统中都是惰性的，并且每单位重量具有很高的活性。利用这种反应性树脂，通过酶与底物在合适介质中的瞬时接触，能够迅速催化酶反应。反应可以在间歇桨液反应器中进行，甚至可以在小柱中进行。无论是哪种情况，不溶性酶都不会污染反应混合物，可以很容易地将其从间歇桨液中滤出或留在色谱柱中。
Features and Benefits
•基质载体上的可回收蛋白酶 K。
•可以利用旋转柱处理或分批处理。
•可以利用旋转柱处理或分批处理。
Physical form
用乳糖稳定化的冻干粉
Other Notes
在pH 7.5、37℃条件下，一单位每分钟可水解尿素变性血红蛋白并产生相当于1.0 μ摩尔 (181 μg) 酪氨酸的显色（使用Folin-Ciocalteu试剂显色）。

The induction of plant immunity by Pathogen Associated Molecular Patterns (PAMPs) constitutes a powerful strategy for crop protection. PAMPs indeed induce general defense responses in plants and thus increase plant resistance to pathogens. Phytophthora infestans culture filtrates (CCFs) are known
