Boc-Gln-Ala-Arg-AMC·HCl is a fluorescent substrate commonly used for the detection of trypsin activity, as well as for measuring the proteolytic activity of TMPRSS2[1]. When specific enzymes act on this substrate, the fluorescent group 7-amido-4-methylcoumarin (AMC) is released. By measuring the fluorescence intensity of AMC, the activity of the enzyme can be quantitatively analyzed. The excitation wavelength of AMC is 380 nm, and its emission wavelength is 460 nm[2].

Boc-Gln-Ala-Arg-AMC·HCl是一种荧光底物,通常用于胰蛋白酶 (trypsin)活性检测,也可用于测定TMPRSS2的蛋白水解活性[1]。当特定酶作用于该底物时,会释放出荧光团7-amido-4-methylcoumarin (AMC),通过测量AMC的荧光强度可以定量分析酶的活性。AMC的激发波长为380 nm,发射波长为460 nm[2]。
