使用 EnzChek 半胱天冬酶-3 活性检测试剂盒,能够简单可靠地检测半胱天冬酶-3 活性介导的细胞凋亡,该试剂盒利用了经过特殊设计的底物,这些底物经半胱天冬酶-3 酶切割后可发出荧光。EnzChek 半胱天冬酶-3 活性检测试剂盒可与 Z-DEVD-AMC 或 Z-DEVD-R110 底物一起使用,这些底物经半胱天冬酶 3/7 蛋白水解切割后产生明亮的荧光产物。
EnzChek 半胱天冬酶-3 活性检测试剂盒通过提供一种简单可靠的半胱天冬酶-3/7 活性检测方法来检测细胞凋亡情况。通过荧光计或荧光微孔板读数仪,该试剂盒可用于连续测定细胞提取物和纯化酶制剂中的半胱天冬酶-3/7 活性。

EnzChek 半胱天冬酶-3 活性检测试剂盒的主要特点包括:
• 使用标准荧光素 (FITC) 激发/发射设置进行荧光检测
• 使用该规格可连续测定细胞提取物中的半胱天冬酶-3/7 活性
• 含有荧光和酶对照品

EnzChek 半胱天冬酶-3 活性检测试剂盒中包含的氨基甲基香豆素 (AMC)-衍生底物(Z-天冬氨酸-谷氨酸-缬氨酸-天冬氨酸 (DEVD)-AMC)在紫外范围内会发出微弱荧光(最大激发/发射波长 ˜330/390 nm),蛋白水解后可产生明亮的蓝色荧光产物(最大激发/发射波长 ˜342/441 nm)。通过荧光计或荧光微孔板读数仪,该试剂盒可用于连续测定细胞提取物和纯化酶制剂中的半胱天冬酶-3 及密切相关的蛋白酶的活性。

EnzChek 半胱天冬酶-3 活性检测试剂盒中使用的罗丹明 110 衍生底物 (Z-DEVD-R110) 是一种非荧光双酰胺化合物,可在两步法过程中通过酶促切割转化为荧光单酰胺,然后再转化为具有更强荧光的 R110 产物。这两种水解产物的光谱特性与荧光素相似,峰值激发和发射波长分别为 496 nm 和 520 nm。

除底物外,EnzChek 半胱天冬酶活性检测试剂盒还含有可逆醛抑制剂 Ac-DEVD-CHO 以及一种 AMC 或 R110 参考标准品。Ac-DEVD-CHO 抑制剂证实,诱导细胞群和对照细胞群中的荧光信号均归因于半胱天冬酶-3/7 蛋白酶的活性。使用参考标准品可定量测定反应中释放的 AMC 或 R110 含量。

常见问题解答 (FAQ)

I am planning to use the EnzChek Caspase-3 Assay Kit #1 with Z-DEVD-AMC substrate. What are the fluorescence excitation/emission maxima of the cleaved substrate?

The basis for the EnzChek Caspase-3 Assay is the 7-amino-4-methylcoumarin-derived substrate Z-DEVD-AMC (where Z represents a benzyloxycarbonyl group), which is weakly fluorescent in the UV range (excitation/emission ~330/390 nm), but yields a bright blue fluorescent product (excitation/emission ~342/441 nm) upon proteolytic cleavage. Measure the fluorescence (excitation/emission ~342/441 nm) using appropriate excitation and emission filters or settings.
