DMAO 是一种细胞膜可穿透型 DNA 荧光染料,非常适合对活菌与死菌进行染色。该染料可标记革兰氏阳性菌、革兰氏阴性菌全部菌株,染色后的细胞可通过荧光显微镜或流式细胞仪检测。
• 绿色膜通透性 DNA 染料
• 可同时对活菌、死菌染色
• 适配荧光显微镜、流式细胞仪检测
与 SYBR 系列染料不同,DMAO 化学稳定性优异,常规操作、室温长期存放均不会发生降解。DMAO 能够穿透活细胞与死细胞的细胞膜,优先结合双链 DNA 并发出绿色荧光。该染料染色活酵母时无细胞核特异性;作用于哺乳动物活细胞时,细胞核与细胞质均会着色。

DMAO is a membrane-permeable DNA dye, excellent for staining live and dead bacteria. It is able to stain both gram positive and gram negative strains, and stained cells can be detected by fluorescence microscopy or flow cytometry.
• Membrane permeable green DNA stain
• Stains both live and dead bacteria
• Detect by fluorescence microscopy and flow cytometry
Unlike the SYBR dyes, DMAO is extremely stable and can be routinely handled and stored at room temperature without degradation. DMAO will permeate the membrane of live and dead cells to preferentially bind dsDNA with green fluorescence. DMAO staining in live yeast is not nuclear. In live mammalian cells, DMAO shows both nuclear and cytoplasmic staining.
