Description

Z-Ala-Ala-Asn-AMC (Cbz-Ala-Ala-Asn-AMC) is a synthetic fluorogenic peptide substrate that releases highly fluorescent AMC upon cleavage by proteases (Ex/Em: 380nm/430nm), which is widely used for the detection of asparaginyl endopeptidase (Legumain) activity[1,2,3]. Legumain is often overexpressed in tumors[4], and Z-Ala-Ala-Asn-AMC serves as a substrate suitable for detecting and quantifying legumain activity in biological samples, high-throughput inhibitor screening, and enzyme kinetics studies[5,6,7].

实验参考方法

使用Z-Ala-Ala-Asn-AMC测定重组Legumain的活性[1]

(1)取10μL Legumain(0.6mg/mL)分别与50μL不同活化缓冲液(含50mM乙酸钠和100mM NaCl,pH 4)混合,于37℃预孵育2h。

(2)随后用测定缓冲液(50mM MES,250mM NaCl,pH 5)将样品稀释至1ng/μL。

(3)加入30μL 150μM Z-Ala-Ala-Asn-AMC,使用酶标仪在380nm和430nm波长下测定酶活性。

(4)分别以每2min读取一次的方式,循环测定20次。酶活性单位定义为在37℃下每分钟释放1μM AMC所需的活性。
