Application
- To label and further investigate the exosomes expelled from cells in triple-negative breast cancer condition.
- To label apoptotic cells, in order to study the role of ανβ5 receptor in both binding and internalization of apoptotic cells.
- In fluorescence imaging.
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.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
Does the dye leak from the cells after labeling when using Product PKH67GL, PKH67 Green Fluorescent Cell Linker Kit for General Cell Membrane Labeling?
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?
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?
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?
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.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
What is the difference between Green Fluorescent Cell Linker Kits PKH2 and PKH67?
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.
How many cells can be stained with Product PKH67GL, Green Fluorescent Cell Linker Kit?
This kit can stain 50 × 107 cells if used as directed (1 × 107 cells stained with 2 × 10-6 M PKH67).
What is the excitation and emission spectra for Product PKH67GL, Green Fluorescent Cell Linker Kit?
The spectra can be found on the product insert.The product has a maximum excitation at 490 nm and maximum emission at 502 nm.
Will Product PKH67, Green Fluorescent Cell Linker Kit, stain dead cells?
As long as the cell has an intact membrane, the PKH76 dye can label the cell.
