La carbocianina lipofílica SP-DiIC₁₈(3) con fluorescencia de naranja es un analógico DiI que contiene grupos de sulfonatos para mejorar la solubilidad en agua. Es débilmente fluorescente en agua, pero muy fluorescente y bastante fotoestable cuando se incorpora a membranas. Los grupos de sulfonatos incorporados en este analógico del DiI mejoran la solubilidad en agua. Tiene un coeficiente de extinción extremadamente alto y tiempos de vida de estado excitado cortos (∼ 1 nanosegundo) en entornos lipídicos. Una vez aplicado a las células, el colorante se difunde lateralmente dentro de la membrana plasmática.

Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes

I stained my cells with a lipophilic cyanine dye, like DiI, but the signal was lost when I tried to follow up with antibody labeling. Why?

Since these dyes insert into lipid membranes, any disruption of the membranes leads to loss of the dye. This includes permeabilization with detergents like Triton X-100 or organic solvents like methanol. Permeabilization is necessary for intracellular antibody labeling, leading to loss of the dye. Instead, a reactive dye such as CFDA SE should be used to allow for covalent attachment to cellular components, thus providing for better retention upon fixation and permeabilization.

How long does it take for lipophlic tracers to transport along the membrane? How much faster are the FAST lipophilic dyes?

The transport is fairly slow, around 6 mm/day in live tissue and slower in fixed tissue, so diffusion of lipophilic carbocyanine tracers from the point of their application to the terminus of a neuron can take several days to weeks The FAST DiO and DiI analogs (which have unsaturated alkyl tails) can improve transport rate by around 50%.

Which form of the lipophilic tracers (DiO, DiI, DiD, etc) should I use?

Select the dye that is compatible with your available excitation source(s) and emission filter set/channels. The solid, paste and crystal forms can be applied directly to neurons in tissues. For labeling cells in culture or microinjection, the lipophilic dyes in solution or solid form can be used.

I want to label two cell populations and then perform a cell fusion assay. Which reagents are best for imaging this?

Lipophilic cyanine dyes are preferred for this sort of assay, since they insert into cellular membranes and then, upon fusion, are shared by the fused cells as the membranes are shared. For example, one cell population can be labeled with DiI (orange-red) and another cell population can be labeled with DiO (green), and when the cells fuse, the combined color appears yellow (when imaged with a dual-bandpass filter set).

'New neurons are continuously added in specific regions of the adult mammalian central nervous system. These neurons are derived from multipotent stem cells whose identity has been enigmatic. In this work, we present evidence that ependymal cells are neural stem cells. Ependymal cells give rise to a rapidly proliferating cell ... More

Suitability of various membrane lipophilic probes for the detection of trogocytosis by flow cytometry.

Trogocytosis is a recently discovered phenomenon whereby lymphocytes capture fragments of the plasma membrane from antigen presenting cells (APCs). Using APCs labeled with widely used fluorescent lipophilic probes, we previously described a trogocytosis analysis protocol (TRAP) useful to understand the mechanisms and biological consequences of this process and to identify ...

Molecules that physiologically control cell proliferation are often produced locally in tissues and are rapidly destroyed when they enter circulation. This allows local effects while avoiding interference with other systems. Unfortunately, it also limits the therapeutic use of these molecules via systemic delivery. We here demonstrate that, for the purpose ... More
