Hoechst 34580细胞核染料，用于在荧光显微镜中标记DNA。 因为这些荧光染色标记DNA，它们也常用于可视化细胞核和线粒体。 通常使用这些密切相关的双苯并酰亚胺中的两种，Hoechst 33258和Hoechst 33342。 两种染料都被约350nm的紫外光激发，并且都发射蓝/青色荧光，发射值为461nm。 Hoechst染色剂可以与活细胞或固定细胞一起使用，并且通常用作另一种核酸染色剂DAPI的替代物。 它们之间的关键区别在于Hoechst 33342的额外乙基使其更具亲脂性，因此更容易穿过完整的细胞膜。在某些应用中，Hoechst 33258的渗透性明显低于Hoechst 33342。这些染料也可用于通过绘制标准的发射 - 含量曲线来检测样品DNA的含量。百萤生物是AAT Bioquest的中国代理商，为您提供的Hoechst 33342细胞核染料。
