Cell Navigator® Live Cell Endoplasmic Reticulum (ER) Staining Kit *Green Fluorescence*
The endoplasmic reticulum (ER) is a type of organelle in the cells of eukaryotic organisms that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. The membranes of the ER are continuous with the outer nuclear membrane. ER occurs in most types of eukaryotic cells, but is absent from red blood cells and spermatozoa. This Cell Navigator® Live Cell Endoplasmic Reticulum (ER) Staining Kit uses our ER Tracer™ Green as an ER marker. ER Tracer™ Green stain is a cell-permeant fluorescent dye that is highly selective for ER. This stain consists of a green fluorescent dye and ER binder that selectively bind to ER in most of cell types. For some cells, ER Tracer™ Green may not selectively bind to ER. ER Tracer™ Green has spectral properties essentially identical to FITC, making this kit convenient with the FITC filter set.

Protocol Summary
- Prepare cells in growth medium
- Incubate cells with ER Tracer™ Green working solution at 37 °C for 15 - 30 minutes
- Analyze the cells under fluorescence microscope at Ex/Em = 490/520 nm (FITC filter set)

PREPARATION OF STOCK SOLUTIONS
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.
Note 20 µL of 500X ER Tracer™ Green stock solution is enough for one 96-well plate. Unused 500X ER Tracer™ Green stock solution can be stored at ≤ -20 ºC for two weeks if the tubes are sealed tightly. Protect from light.
ER Tracer™ Green stock solution (500X)
Add 20 µL of DMSO (Component C) into the vial of ER Tracer™ Green (Component A) and mix well to make 500X ER Tracer™ Green stock solution.Note 20 µL of 500X ER Tracer™ Green stock solution is enough for one 96-well plate. Unused 500X ER Tracer™ Green stock solution can be stored at ≤ -20 ºC for two weeks if the tubes are sealed tightly. Protect from light.
PREPARATION OF WORKING SOLUTION
ER Tracer™ Green working solution
Add 20 µL of 500X ER Tracer™ Green stock solution into 10 mL of Live Cell Staining Buffer (Component B), and mix well to make ER Tracer™ Green working solution.Note This ER Tracer™ Green working solution is stable for at least 2 hours at room temperature. Protect from light.
SAMPLE EXPERIMENTAL PROTOCOL
- Add 100 µL/well (96-well plate) or 50 µL/well (384-well plate) of ER Tracer™ Green working solution in the cell plate. Incubate cells with working solution at 37 °C for 15 - 30 minutes, protected from light.
Note The optimal concentration of the ER probe varies depending on the specific application. Concentration higher than the working solution can be toxic to cells. The staining conditions may be modified according to the particular cell type and the permeability of the cells or tissues to the probe. - Remove ER Tracer ™Green working solution in each well. Wash cells with physically relevant buffer three times.
- Fix cells after staining (Optional). Fix the cells with 4% formaldehyde for 5 - 10 minutes. Wash cells with physically relevant buffer three times.
- Observe the fluorescence signal in cells using fluorescence microscope with FITC filter set (Ex/Em = 490/520 nm).
