Application
Il kit PKH67 Green Fluorescent Cell Linker per la marcatura aspecifica della membrana cellulare è stato utilizzato:
- per marcare e quindi studiare gli esosomi espulsi dalle cellule nel cancro della mammella triplo negativo[1]
- per marcare le cellule apoptotiche[2] al fine di studiare il ruolo del recettore ανβ5 nel legame e nell′internalizzazione delle cellule apoptotiche[3]
- nell′imaging in fluorescenza.[4]
Il kit serve alla marcatura generale delle membrane cellulari. Il PKH67 ha una coda di carbonio alifatica più lunga del PKH1 e del PKH2, gli altri due coloranti verdi precedentemente descritti per il tracking cellulare in vitro e in vivo. Sulla base della maggiore lunghezza della coda, gli studi in-house hanno mostrato costantemente un trasferimento cellula-cellula ridotto per il PKH67 rispetto al PKH2.
È stata osservata una lenta perdita di fluorescenza negli studi condotti in vivo con PKH1 e PKH2. Il PKH67 può mostrare proprietà simili dal momento che questo comportamento sembra essere caratteristico dei coloranti linker cellulari verdi ma non di quelli rossi. La correlazione tra la ritenzione della membrana cellulare in vitro e l′emivita della fluorescenza in vivo nelle cellule che non si dividono prevede un′emivita della fluorescenza in vivo di 10-12 giorni per il PKH67. Altri coloranti linker cellulari con emivite analoghe sono stati utilizzati per monitorare il traffico di linfociti e macrofagi in vivo nell′arco di 1-2 mesi. Questo suggerisce che il PKH67 potrebbe essere utile anche per gli studi di tracking in vivo di durata moderata.

Optimal staining is a key component for studying tumorigenesis and progression. Learn useful tips and techniques for dye applications, including examples from recent studies.
PKH and CellVue® Fluorescent Cell Linker Kits provide fluorescent labeling of live cells over an extended period of time, with no apparent toxic effects.
PKH dyes are easy to use and achieve stable, uniform, and reproducible fluorescent labeling of live cells. PKH dyes are non-toxic membrane stains which produce high signal to noise ratio.

I mark mitochondria for injection with PKH26 Red Fluorescent Cell Linker Kit for General Cell Membrane Labeling. I want to use another dye to mark another type of mitochondria and inject them together in the same fish egg. Is PKH67 ok for this like PKH26?

What can be the alternative for removing excess dye after labeling of exosomes using PKH67 dye apart from ultracentrifugation?
1 risposta-
Excess dye is bound to serum or albumin which is added to the cell/dye mixture as a stop reaction. The recommended clean up or dye removal is by standard centrifugation (400 x g for 10 minutes, wash, and repeat). See the Product Information Sheet, page 3, bullet point 8 for more information:
https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/984/984/pkh67glbul.pdfAlternate methods for excess dye removal have not been investigated.

Can we remove the excess PKH67 DYE used for the labeling of exosomes using exosome spin column rather than ultracentrifugation.
1 risposta-
The recommended exosome labeling protocol has been optimized to assure the best possible results. The use of exosome spin columns with the PKH and CellVue products has not been validated. See below for a link to our exosome labeling protocol. A spin column method may not offer the best results.

When using Product PKH67GL, PKH67 Green Fluorescent Cell Linker Kit for General Cell Membrane Labeling, how long will the cells remain stained after treatment?
1 risposta-
Labeled cells that have been washed can be visualized in culture up to 100 days after staining (for non-dividing cells). The dye itself is stable and will divide equally when the cells divide. After staining with PKH dyes, you can observe as many as 8 divisions depending on how brightly the cells were stained initially and the amount of surface area on the cells. Most commonly, 4-6 divisions can be visualized.

What method of fixation can be used for tissue/cells with the PKH Fluorescent Cell Linker Kit for General Cell Membrane Labeling dyes?
1 risposta-
A protocol for visualization of tissue sections can be found in the technical bulletin. For visualization of stained cells by immunofluorescence or flow cytometry, the cells can be fixed in 2% paraformaldehyde for 15 minutes. The use of other organic solvents will extract the dye from the cells. If internal labeling is desired, the cells can be permeabilized with saponin (50-75 μg/mL). Here is the link to the Troubleshooting Guide.
