Descripción

General description

The BioTracker^™ Membright-640 live cell dye is a “turn-on” fluorescence probe emitting in the far red spectrum for the imaging of plasma membranes of live cells.

Probes specific for the plasma membrane are fundamental tools for marking cell boundaries. Membright probes use a unique mechanism, existing in a self-quenched nanoparticle state. On contact and propagation within the cell membrane, the probe becomes fluorogenic, demonstrating remarkably high signal-to-background ratio. These live cell membrane probes are compatible with two-photon imaging, superresolution imaging, and are suitable for use in live or fixed cells. Their exceptional photostability and lack of cytotoxicity make Membright probes optimal for long-term imaging studies. The key characteristics of these plasma membrane probes permit use in a broad spectrum of fluorescence microscopy applications, and in flow cytometry.

Spectral Properties
