ER-Tracker Red

ER-Tracker dye is a derivative of BODIPY conjugated with Glibenclamide, displaying high selectivity for the endoplasmic reticulum. At low concentrations, it remains non-toxic to cells and serves as an environmentally sensitive probe that retains some fluorescence after formaldehyde treatment. It is characterized by its high fluorescence lifetime and strong extinction coefficient. Glibenclamide acts as an ATP-dependent K+ channel blocker (Kir6, KATP) and a CFTR Cl- channel blocker, binding within the endoplasmic reticulum. ER-Tracker is not suitable for staining fixed cells. Ex/Em = 587/615 nm.
