Description

General description

The BioTracker^™ Membright-560 live cell dye is a “turn-on” fluorescence probe emitting in the orange to red spectrum for imaging of plasma membranes of live cells.

Probes specific for the plasma membrane are essential for demarcating cell boundaries. Membright dyes use a novel fluorogenic mechanism, operating in a self-quenched nanoparticle state. On contact and propagation within the cell membrane, fluorescence is turned on, producing a bright signal with low to no background. The Membright live cell membrane probes are compatible with two-photon imaging, superresolution microscopy, and can be used in live or fixed cells. Their robust photostability and lack of cytotoxicity make Membright probes optimal for protracted live cell imaging. The superior characteristics of these plasma membrane probes permit use in a diverse spectrum of fluorescence detection applications.

Spectral Properties
Fluorescence images obtained by λex = 560 nm and emission range of 567-750 nm.
