ER-Tracker dye is an analogue of the BODIPY series dye coupled with Glibenclamide. It binds to the endoplasmic reticulum with high selectivity and is non-toxic to cells at low concentrations. This type of dye is an environmentally sensitive probe. After treatment with formaldehyde It can still retain part of the fluorescence and has the characteristics of high fluorescence lifetime and good extinction coefficient. Glibenclamide is an ATP-dependent K+ channel blocker (Kir6, KATP) and CFTR Cl- channel blocker that binds in the endoplasmic reticulum. ER-Tracker is not suitable for staining fixed cells.

Biological Activity


ln Vitro 1. The ER-Tracker working solution is prepared as follows: 1.1 Stock solution preparation: dissolve 100 μg of ER-Tracker in 128 μL DMSO to create a 1 mM stock solution. Note: It is advised to keep the stock solution frozen and to avoid repeatedly thawing and freezing it at -20°C or -80°C in the dark. 1.2 Making the working solution for ER-Tracker Dilute the stock solution to a concentration of 100 nM-1 μM using either PBS or serum-free cell culture medium. It is important that you modify the ER-Tracker working fluid concentration based on the current circumstances. 2. Suspension cells in a 6-well plate (2.1) are stained A. After three to five minutes at 4°C and 1000 g of centrifugation, discard the supernatant. Wash for five minutes each time, twice, using PBS. One x 10^6 cells per milliliter. B. After adding 1 mL of the working solution, let it sit at room temperature for five to thirty minutes. an. Discard the supernatant after centrifuging for three to four minutes at 400 g and 4°C. D. Wash for five minutes each time, twice, using PBS. E. In PBS or serum-free cell culture media, resuspend the cells. either flow cytometry monitoring or fluorescence microscopy. Cells that adhere 2.2 a. Adherent cells are cultured on sterile coverslips. B. Lift the coverslip out of the culture media and use the aspirator to remove any extra. an. To fully cover the cells, add 100 μL of working solution, shake gently, and then incubate for five to thirty minutes at room temperature. D. Use medium for five minutes each time you wash. either flow cytometry monitoring or fluorescence microscopy. Note: Cells must be resuspended prior to staining if flow cytometry is being used for detection.

Solubility Data


Solubility (In Vitro) DMSO: 50 mg/mL (63.85 mM)
Solubility (In Vivo) Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
