过氧化氢特异性荧光探针BES-H2O2-Ac / BES-H 2O2
• 比二氯荧光黄 (DCFH) 有更高的特异性
• 可动态监测活细胞内的过氧化氢
• BES-H2O2-Ac 可穿透细胞膜，无需打孔
• 极易溶于水，可制成水溶液使用
• 可用于荧光显微镜、流式细胞仪

BES-So-AM：使用举例

图1）是Jurkat T细胞在含33μM BES-So-AM的培养基中37°C培养1小时，使探针进入细胞，然后添加4mM丁酸（O2•-诱导剂），37°C培养1小时；图2）是Jurkat T细胞在含33μM BES-So-AM的培养基中37°C培养1小时，使探针进入细胞，然后不添加丁酸，37°C再培养1小时；图3）是Jurkat T细胞在含33μM BES-So-AM的培养基中37°C培养1小时，然后添加5mM的丁酸，继续培养一个小时。参考文献

•Much higher selectivity compared to conventionally-used DCFH probes•Responds specifically to hydrogen peroxide, enabling detection of intracellular hydrogen peroxide activity•BES-H2O2-Ac is cell membrane permeable•Superior water solubility allows use with aqueous solutions•Can be used in flow cytometry

2. Application

H2O2-produced stimulation No H2O2-produced stimulation
Fluorescent images
Phase-contrast images
Fluorescent images of Jurkat T cells with BES- H2O2 -Ac and the same-fi eld phase-contrast images
Jurkat T cells were cultured in a medium with 50μM BES-H2O2-Ac for 1 hour. Then, one group of them was cultured in a medium with 5 mM butyric acid (H2O2-produced stimulation), whereas the other in a medium without butyric acid (No H2O2- produced stimulation), each for 1 hour.
