简要概述

磷酸二酯酶PDE IV底物 FAM-cAMP 绿色荧光 是美国AAT Bioquest生产的荧光底物，这种绿色荧光cAMP衍生物是磷酸二酯酶（PDE）IV的特定底物。它可用于检测PDE IV活性或与FRET读数或FP格式的抗cAMP抗体一起筛选PDE IV抑制剂。 PDE是一组降解第二种信使分子的酶：环状核苷酸cAMP和cGMP。它们调节亚细胞域内环状核苷酸信号传导的定位，持续时间和幅度。因此，PDE是这些第二信使分子介导的信号转导的重要调节剂。 PDE酶由于其独特的组织分布，结构和功能特性，经常成为药理抑制的靶标。 PDE抑制剂可通过抑制PDE的降解来延长或增强cAMP或cGMP介导的生理过程的作用。在诸如肺动脉高压，冠心病，痴呆，抑郁症和精神分裂症等领域，PDE抑制剂被确定为新的潜在治疗剂。金畔生物是AAT Bioquest的中国代理商，为您提供最优质的磷酸二酯酶PDE IV底物 FAM-cAMP 绿色荧光 。

样品实验方案 

溶液制备 

1.储备溶液

所有未使用的储备溶液应分为一次性使用的等分试样，并在制备后储存在-20°C下。 避免重复冻融循环。
1.1 FAM-cAMP PDE IV储备溶液（1 mM）：
将500 µL DMSO加入0.5 umol FAM-cAMP PDE IV底物瓶中，制成1 mM储备液。

2.工作溶液

FAM-Cyclic-3’，5′-AMP PDE IV底物测定溶液（2X）：
通过将1 mM FAM-Cyclic-3’，5′-AMP PDE IV底物储备溶液稀释到您的PDE缓冲液（例如10 mM Tris-HCl）中，制成2X FAM-Cyclic-3’，5′-AMP PDE IV底物测定溶液 ，pH 7.4、10 mM的Mg Cl2、1 mM的MnCl2）制成200-400 nM的溶液。 注意：仅进行测定所需的足够数量。

样品操作及分析

1.将等体积的PDE IV标准品或样品与2X FAM-Cyclic-3’，5′-AMP PDE IV底物测定溶液混合，并在室温下孵育至少1小时。

2.在Ex / Em = 490/525 nm处监测荧光偏振。
