LumiTracker ER Red (also known as ER-Tracker™ Red) is a cell-permeant, highly selective for the endoplasmic reticulum (ER) stain for live cell imaging. LumiTracker ER Red is a derivative of red-fluorescent BDP TR dye coupled with Glibenclamide (Glyburide). Glibenclamide binds to the sulphonylurea (SUR) receptors of ATP-sensitive potassium channels (K_ATP), which are prominent on the endoplasmic reticulum. The staining is partially retained after fixation with formaldehyde. LumiTracker ER Red is not suitable for staining cells after fixation.

Note that the pharmacological activity of glibenclamide could potentially affect ER function. Variable expression of sulphonylurea receptors in some specialized cell types may result in non-ER labeling.

LumiTracker® Lyso Blue

Blue-emitting reagent for labeling and tracking lysosomes and other acidic organelles with low internal pH in live cells. Analog of LysoTracker™ Blue DND-22.

Cyanine5 tetrazine

Cyanine5 is a universal red emitting dye with a very high extinction coefficient, and good quantum yield. This tetrazine derivative reacts very quickly with trans-cyclooctenes and cyclopropenes with the formation of stable conjugates.
