Cell movement and location studies require specialized probes that are nontoxic to living cells and well retained, allowing for multigenerational tracking. The CellTracker fluorescent probes are available in a range of fluorescent colors to match instrument lasers and filters, and to accommodate co-staining with antibodies or other cell analysis probes. These dyes are excellent tools for monitoring cell movement, location, proliferation, migration, chemotaxis, and invasion.

Este colorante se conserva bien, lo que permite el seguimiento multigeneracional de movimientos celulares.
Los espectros de excitación/emisión verde (492/517 nm maxima) son ideales para el multiplexing con proteínas y colorantes rojo fluorescente.
Fácil de usar: retire el medio, añada el colorante, incube 30 minutos y obtenga la imagen de las células.
Retención de la señal fluorescente superior a >72 horas (normalmente de tres a seis generaciones).
Baja citotoxicidad: no afecta a la viabilidad ni a la proliferación
El tinte fluorescente de CMAC CellTracker Blue se ha diseñado para atravesar libremente las membranas celulares hasta las células donde se transforma en productos de reacción impermeabilizantes de membranas celulares.
El colorante se transfiere a las células hijas, pero no a las celdas adyacentes de una población.
Estable, no tóxico a las concentraciones de trabajo, bien conservado en las células, y brillante fluorescente a pH fisiológico

Preguntas frecuentes

I want a dye that can track cells similar to CFSE, but excited with 405 nm violet laser. What is available?

CellTrace Violet and CellTracker Violet BMQC work in the same way as CFSE, but are efficiently excited with the violet laser. They are comparable to CFSE in terms of cell retention, and has been used for tracking cells with microscopy as well as flow cytometry.

I want to do a cell migration study for around 4 hours and need to fluorescently label the cells with a dye. What do you recommend?

Calcein, AM and FDA (fluorescein diaceate) are examples of some dyes used for this application. Since these dyes are not incorporated or covalently attached to any cellular components, they may have a short retention time as some cell types may actively efflux the dye out of the cells. The CellTracker and CellTrace dyes include either a mild thiol-reactive chloromethyl group or amine-reactive succinnimidyl ester group to allow for covalent binding to cellular components, providing for better retention. As with any reagent, one should empirically determine retention times for the cell type used.

I labeled my cells with Calcein, AM, but when I imaged the next day, there was no fluorescence from Calcein. Why?

Calcein, AM is a good choice for cell tracking and as a general cytoplasmic stain. However, it doesn't bind to anything and may be actively pumped out of the cells within a couple hours, which is likely what happened. The retention of Calcein within live cells is dependent upon the inherent properties of the cell type and culture conditions.

For long-term imaging, you may wish to consider a reactive cytoplasmic stains such as CFDA, SE or the CellTracker and CellTrace dyes.

Can the CellTracker dyes be fixed?

Yes, the CellTracker dyes react with any accessible thiol part of the protein and can be fixed. However, some CellTracker dyes may be attached to small metabolites that can leak from the cell following permeabilization. This can result in decreased fluorescence.

I stained two populations of cells, one with CellTracker Green and the other with CellTracker Red, but it looks like there may be crossover of the red dye to the green cells. What is going on?

One possibility is that there is spectral bleedthrough between the dyes. Be sure to check the single-color samples by imaging the red cells in green and imaging the green cells in red, using the optimal imaging settings for the other color. If you see bleedthrough with these controls, then you will have to reduce the dye label concentration to reduce the brightness of the dyes, or choose dyes that are farther apart spectrally. If the issue isn’t bleedthrough, another possibility is that the cells were not adequately washed after staining, allowing some unincorporated dye to remain and label the other cells after they were introduced. Extending washes and wash times should help with this.

Abstract

Different modalities of intercellular membrane exchanges mediate cell-to-cell p-glycoprotein transfers in MCF-7 breast cancer cells.

'Multi-drug resistance (MDR) is a phenomenon by which tumor cells exhibit resistance to a variety of chemically unrelated chemotherapeutic drugs. The classical form of multidrug resistance is connected to overexpression of membrane P-glycoprotein (P-gp), which acts as an energy dependent drug efflux pump. P-glycoprotein expression is known to be controlled ... More
