7-叠氮基-4-甲基香豆素（AzMC）是一种可用于检测硫化氢（H2S）的荧光探针。 在H2S存在下可选择性地还原芳族叠氮部分，产生荧光7-氨基-4-甲基香豆素（AMC）以及在λex = 365nm和λem = 450nm处的荧光增加。该探针既可用于体外监测H2S的酶促产生，也可用于观察细胞中的H2S。该探针对H2S具有高度的敏感性和选择性，可在体外利用10μM探针提供200nm – 100μM H2S的线性检测范围，并在mM浓度的半胱氨酸、同型半胱氨酸、谷胱甘肽和多种其他常见的生物分析物的存在下选择性地与H2S进行反应。
注意：应避免将该产品与DTT、TCEP或>25mM的生物硫醇一起使用，以获得最大效率。
AzMC可溶于DMSO中。

Hydrogen sulfide (H2S) is an endogenously produced signaling molecule. The enzymes 3-mercaptopyruvate sulfurtransferase (MST), partly localized in mitochondria, and the inner mitochondrial membrane-associated sulfide:quinone oxidoreductase (SQR), besides being respectively involved in the synthesis and catabolism of H2S, generate sulfane sulfur
