常见问题解答 (FAQ)

我用DiI一类的亲脂性花青染料进行细胞染色,但是当我试图继续用抗体标记时信号却丢失了。 这是什么原因所致?

由于这些染料插入脂质膜,任何对膜的破坏都将导致染料流失。这包括用Triton X-100之类的去垢剂或是甲醇之类的有机溶剂通透。通透是胞内抗体标记所必需的,但它会导致染料流失。相反,CFDA SE之类活性染料能够共价连接到细胞组分,因此可以在固定和通透之后更好的保留。

亲脂性示踪剂跨膜转运需要多久?FAST亲脂性染料能快多少?

转运过程相当缓慢:在活体组织中大约6 mm/天,在固定组织中更慢。亲脂性羰花青示踪剂从开始给样处扩散到神经元末端,可能需要数天甚至数周的时间。FAST DIO和DiI类似物(具有不饱和烷基尾)可以提高50%左右的转运速度。

我应该使用哪种亲脂性示踪剂(DiO、DiI、DiD等)?

请选择与您现有的激发光源和发射滤光片组/通道兼容的染料。固体、糊和晶体形式的染料可直接施加到组织中的神经元。如需标记培养的细胞或进行显微注射,可采用溶液或固态形式的亲脂性染料。

我想标记两种细胞群体然后进行细胞融合实验,哪种试剂最适合来成像?

亲脂性花青染料非常适合此类测定,因为它们会掺入到细胞膜中,随着细胞融合之后共用细胞膜,染料也随之共享。例如,一个细胞群体可以用DiI(橙红色)进行标记,而另一细胞群可以用DIO(绿色)进行标记,当细胞融合时合并的颜色为黄色(使用双带通滤光片成像)。

我想用核酸染料来追踪我的细胞,比如DAPI或者Hoechst染料。您有什么建议吗?

这是不推荐的。这些染料与DNA和RNA的结合会影响核酸的正常功能,扰乱转录和增殖。诸如CellTracker染料或Qtracker试剂在不严重扰乱细胞正常活动的条件下对其进行追踪。如果您仍需要使用核酸染料进行标记且细胞是哺乳动物和非血液来源的话,CellLight 细胞核试剂可通过瞬时转染进入细胞,在核表达蛋白上表达GFP或RFP长达数天而不影响其功能。

High spatial resolution confocal microscopy of young MDCK cells stained with the lipophilic probe 1,1'-dihexadecyl-3,3,3',3'- tetramethylindocarbocyanine perchlorate (DiIC(16)) revealed a reticulated fluorescence pattern on the apical membrane. DiIC(16) was delivered as crystals to live cells to minimize possible solvent perturbations of the membrane lipids. The ratio of the integrated fluorescence ... More

The desorption rate constants for a cationic dye from strong adsorption sites are compared for the same chromatographic interface but for two different substrates, fused silica and chromatographic silica gel. The dye is 1,1'-didodecyl-3,3,3'3'-tetramethylindocarbocyanine perchlorate (DiI). The interface consists of acetonitrile and a hydrocarbon monolayer (C8) covalently bound to the ... More
