Hoechst 34580細胞核染料，用于在熒光顯微鏡中標(biāo)記DNA。 因為這些熒光染色標(biāo)記DNA，它們也常用于可視化細胞核和線粒體。 通常使用這些密切相關(guān)的雙苯并酰亞胺中的兩種，Hoechst 33258和Hoechst 33342。 兩種染料都被約350nm的紫外光激發(fā)，并且都發(fā)射藍/青色熒光，發(fā)射值為461nm。 Hoechst染色劑可以與活細胞或固定細胞一起使用，并且通常用作另一種核酸染色劑DAPI的替代物。 它們之間的關(guān)鍵區(qū)別在于Hoechst 33342的額外乙基使其更具親脂性，因此更容易穿過完整的細胞膜。在某些應(yīng)用中，Hoechst 33258的滲透性明顯低于Hoechst 33342。這些染料也可用于通過繪制標(biāo)準的發(fā)射 - 含量曲線來檢測樣品DNA的含量。百螢生物是AAT Bioquest的中國代理商，為您提供的Hoechst 33342細胞核染料。
