Application
- To label and further investigate the exosomes expelled from cells in triple-negative breast cancer condition.[1]
- To label apoptotic cells,[2] in order to study the role of ανβ5 receptor in both binding and internalization of apoptotic cells.[3]
- In fluorescence imaging.[4]
Slow loss of fluorescence has been observed in in vivo studies using PKH1 and PKH2. PKH67 may exhibit similar properties since this behavior appears to be characteristic of green cell linker dyes, but not red cell linker dyes. Correlation of in vitro cell membrane retention with in vivo fluorescence half life in non-dividing cells predicts an in vivo fluorescence half life of 10-12 days for PKH67. Other green cell linker dyes with similar half lives have been used to monitor in vivo lymphocyte and macrophage trafficking over periods of 1-2 months, suggesting that PKH67 will also be useful for in vivo tracking studies of moderate length.

Lipophilic cell tracking dyes enable cancer biologists to track tumor and immune cell functions both in vitro and in vivo. Read the article to choose a right membrane dye kit for cell tracking and proliferation monitoring.
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 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:

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.

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.

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.

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.

What is the difference between Green Fluorescent Cell Linker Kits PKH2 and PKH67?
1 answer-
PKH2 was one of the early PKH dyes. The PKH67 dye has a longer aliphatic tail. There is reduced cell-celldye transfer for PKH67 as compared with PKH2.
