[In Vitro]

WSP-1 具有荧光特性,激发波长 (ex) 465 nm,发射波长 (em) 515 nm[1]。 Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 细胞内 H2S 的荧光检测 (荧光显微镜检查)[1]: 1. HASMCs 培养至约 90% 聚集,实验前 24 小时,将细胞以 30*103 每孔的密度在 8 孔培养载玻片上培养 24 小时。 2. 更换培养基,加入 WSP-1 工作液 400 μL,37℃ 孵育 30min。 3. 将 WSP-1 工作液替换为 380 μL 标准缓冲液,加入 20 μL 所需浓度的H2S 供体化合物。 4. 当 WSP-1 与 H2S 反应时,释放在 Ex/Em=465/515 nm 下可检测到的荧光团。取缓冲标准品,培养 1 小时后用 400 μL DPBS 洗涤。 5. 去除 DPBS,室温下每孔加入 200 μL Bouin 溶液固定细胞 10 min。去除多余的Bouin溶液,用 400 μL DPBS 清洗细胞 2 次。 6. 用荧光显微镜检查和获取荧光信号。
