FM® 4-64FX, fixable analog of FM® 4-64 membrane stain

Category: Products & Services > Labeling & Detection Products > Cell Stains > Other Cell Stains

The lipophilic probe, FM™ 4-64FX exhibits low fluorescence in water but fluoresces intensely upon binding the outer leaf of the plasma membrane providing discrete plasma membrane staining. The binding is rapid and reversible and "FX" denotes that this analog is fixable with aldehyde-based fixatives. It is also an excellent reagent for identifying actively firing neurons and for investigating the mechanisms of activity-dependent vesicle cycling.

ER-Tracker™ Blue-White DPX, for live-cell imaging

Category: Products & Services > Labeling & Detection Products > Cell Stains > Organelle Stains

ER-Tracker Blue-White DPX dye is a photostable probe that is selective for the endoplasmic reticulum (ER) in live cells. The cells can be aldehyde-fixed after staining with the dye but significant fluorescence signal will be lost. With excitation at ~374 nm, the environmentally-sensitive probe exhibits emission between 430 and 640 nm. A long-pass DAPI filter works best.
