Excitation (nm)
Emission (nm)
The Cell Navigator™ Plasma Membrane Stain Kit provides a fast and uniform labeling of the plasma membrane without the cell-type differences exhibited by lectins. It may be used as a segmentation tool for HCS (high-content screening), as well as to stain cellular plasma membranes for standard fluorescence microscopy. The stain used in the kit survives fixation, but not permeabilization, so it is not suitable for experiments that also involve probing internal targets via antibodies.

Example protocol


Protocol Summary
  1. Prepare cells in growth medium
  2. Incubate cells with Cellpaint™ Orange working solution at 37 ºC for 10 - 20 minutes
  3. Analyze the cells under fluorescence microscope at Ex/Em = 540/590 nm (TRITC filter set) 
Important      Thaw all the kit components at room temperature before starting the experiment.

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

Cellpaint™ Orange stock solution (500X)
Add 100 µL of DMSO (Component C) into the vial of Cellpaint™ Orange (Component A) to make 500X Cellpaint™ Orange stock solution. Note: Unused 500X Cellpaint™ Orange stock solution can be stored at ≤ -20 ºC for one month if the tubes are sealed tightly. Protect from light.


Add 20 µL of 500X Cellpaint™ Orange stock solution into 10 mL of Assay Buffer (Component B) and mix well to make Cellpaint™ Orange working solution. This Cellpaint™ Orange working solution is stable for at least 8 hours at room temperature. Protect from light. Note: 20 µL of 500X Cellpaint™ Orange 500X stock solution is enough for one 96-well plate.


  1. Add 100 µL/well (96-well plate) or 50 µL/well (384-well plate) of Cellpaint™ Orange working solution in the cell plate.
  2. Incubate the cells at 37°C for 10 - 20 minutes, protected from light. Note: The optimal concentration of the cell membrane probe varies depending on the specific application. The staining conditions may be modified according to the particular cell type and the permeability of the cells or tissues to the probe.
  3. Remove Cellpaint™ Orange working solution in each well.
  4. Wash cells with physiological buffer (such as HHBS, PBS or buffer of your choice) for three times.
  5. Fix cells after staining (Optional). Fix the cells with 4% formaldehyde for 15 - 30 minutes. Wash cells with physiological buffer for three times.
  6. Observe the fluorescence signal in cells using a fluorescence microscope with TRITC filter set (Ex/Em = 540/590 nm).
