Application
Bei In-vivo-Studien mit PKH1 und PKH2 wurde ein langsamer Verlust der Fluoreszenz beobachtet. PKH67 kann ähnliche Eigenschaften aufweisen, da dieses Verhalten charakteristisch für grüne Zelllinker-Farbstoffe zu sein scheint, aber nicht für rote Zelllinker-Farbstoffe. Die Korrelation von der In-vitro-Zellmembranrückhaltung mit der In-vivo-Fluoreszenzhalbwertszeit in sich nicht teilenden Zellen berechnet eine In-vivo-Fluoreszenzhalbwertszeit von 10 bis 12 Tagen für PKH67. Andere grüne Zelllinker-Farbstoffe mit ähnlichen Halbwertszeiten werden verwendet, um den In-vivo-Lymphozyten- und -Makrophagentransport über Zeiträume von 1 bis 2 Monaten zu beobachten, was darauf hindeutet, dass PKH67 auch für In-vivo-Verfolgungsstudien von mittlerer Länge geegígnet sind.

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 answer-
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 answer-
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.

What method of fixation can be used for tissue/cells with the PKH Fluorescent Cell Linker Kit for General Cell Membrane Labeling dyes?
1 answer-
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.

Are cells lost during the PKH67 Green Fluorescent Cell Linker Kit for General Cell Membrane Labeling staining process?
1 answer-
Over-labeling of the cells will result in loss of membrane integrity and reduced cell recovery. Methods for improving cell viability can be found on the troubleshooting guide.

Does the dye leak from the cells after labeling when using Product PKH67GL, PKH67 Green Fluorescent Cell Linker Kit for General Cell Membrane Labeling?
1 answer-
In general, slow loss of fluorescence has been observed with PKH1 and PKH2 in in vivo studies and it is likely that PKH67 may also slowly lose fluorescence. Leakage (or loss of staining intensity) may also occur due to cell-to-cell transfer of the dye. The most common cause of cell-to-cell dye transfer is inadequate washing of the cells. Wash cells 3-5 times after labeling and transfer samples to new tubes between washes.

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 answer-
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.
