DiI 是染料 Aye，一种 CAS 号为 41085-99-8 的化学品。它是荧光亲脂性阳离子吲哚菁染料，通常制成高氯酸盐。主要用于科学染色目的，例如单分子成像、命运绘图和神经元追踪（因为 DiI 保留在脂质双层膜中）。 应用: 1，1′-二十八烷基-3，3，3′，3′-四甲基吲哚菁高氯酸盐用于以下应用： DIL 溶液的制备 荧光膜染料 Di-I 染色 1,1'-Dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate is a lipophilic dye used to record membrane voltage for fluidity studies. This retrograde stain is useful in staining neurons in vitro and in vivo because the stain is relatively nontoxic to cell bodies and the dye is retained in neurons. In addition, 1,1'-Dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate is an ideal retrograde and anterograde tracer to label the processes as well as the cell bodies of cultured neurons. A dye used to record membrane voltage.
