产品介绍

Hoechst染料是一类在显微观察中标记DNA的荧光染料。因为这类荧光染料能标记DNA,所以它们也经常用于细胞核和线粒体的显像观察。这类染料中两个相关的染料Hoechst 33258和Hoechst 33342经常使用。这两种染料都在紫外光下350nm处被激发,都在461nm处最大发射光附近发射蓝/青色荧光。Hoechst染料可以用于活细胞或者固定化细胞,并且经常用来代替其它核酸染料如DAPI。这两种染料关键的不同点在于,Hoechst 33342加有乙基,这使它具有更强的亲脂性,因此能更好的透过完整的细胞膜。在一些实验中,Hoechst 33258的渗透性明显比Hoechst 33342要弱些。这些染料也可以用来检测样品中的DNA含量,通过绘制发射光强度与DNA含量的标准曲线。
Hoechst 33342是一种可透过细胞膜并对DNA染色的细胞核染色试剂,它在嵌入双链DNA后释放强烈的蓝色荧光。Hoechst 33342常用于细胞凋亡检测,染色后用荧光显微镜观察或流式细胞仪检测。Hoechst 33342-DNA的激发和发射波长分别为350 nm和460 nm。
Hoechst 33342溶于水,溶解度可达20mg/mL。

Cell-permeable, adenine-thymine-specific fluorescent stain. Useful for staining DNA, chromosomes, and nuclei for fluorescence microscopy and flow cytometry applications. Useful for the simultaneous study of the cell cycle and apoptosis in unfixed cells. Induces cell differentiation. H 33342 and the related compound H 33258 (Cat. No. 382061) have been used in conjunction with RNA aptamers in the 5′ untranslated region (UTR) to control expression of transfected gene constructs. Exhibits a 10-fold greater cell-permeability than H 33258. Cell-permeable adenine-thymidine specific fluorescent stain. Useful for staining DNA, chromosomes or nuclei for fluorescence microscopy and flow cytometry applications. DNA-bound dye has an excitation maximum of 358 nm and an emission maximum of 460 nm. Useful for the simultaneous study of the cell cycle and apoptosis in unfixed cells. Induces cell differentiation. H33342 and the related compound H33258 (Cat. No. 382061) have been used in conjunction with RNA aptamers in the 5′ untranslated region (UTR) to control expression of transfected gene constructs. Exhibits a 10 fold greater cell-permeability than H 33258.
