Application

4′,6-二脒基-2-苯基吲哚二盐酸盐应用于免疫细胞化学和细胞化学中各种细胞的染色，人类皮下脂肪组织的荧光成像、免疫荧光胚胎切片。
在琼脂糖凝胶中染色DNA，DAPI比溴化乙锭敏感几倍。
在琼脂糖凝胶中染色DNA，DAPI比溴化乙锭敏感几倍。它可用于DNA的光足迹图谱，通过对双链复合体的特殊可视化检测印迹应用中的退火探针，并使用流式细胞分析术研究DNA中的变化并分析凋亡过程中的DNA含量。DAPI染色也是一种敏感和特异的支原体检测方法。

Biochem/physiol Actions

DNA的细胞渗透性荧光小沟结合探针。与双链DNA的小沟（富含AT的DNA优先）结合，形成稳定的复合物，其发出的荧光比单独的DAPI高约20倍。

Disclaimer

避光保存。

General description

4′,6-二脒基-2-苯基吲哚二盐酸盐是一种用于DNA染色的荧光染料。它与DNA中富含 dAT（脱氧腺嘌呤-胸腺嘧啶）区域强烈地相互作用。
可能需要加热或超声处理。溶液可在室温或4 °C下避光稳定保存2至3周。
