• Fluorescent, far-red probe for live cell imaging of the plasma membrane
• Fluorescent, far-red probe for fixed cell imaging of the plasma membrane

PKmem 650 labels the plasma membrane in live cells with very high specificity. It has extremely low phototoxicity, due to the presence of the intramolecular triplet quencher cyclooctatetraene (COT) group, enabling long term live cell imaging of the plasma membrane without damaging the cells

Key features

• Ab: 650 nm, Em: 671 nm – far-red spectrum
• Suitable for long term imaging of plasma membranes in live and fixed cells
• Compatible with widefield, confocal or SIM microscopy

The biological activity of CY-SC065 is assessed by the ability of the probe to efficiently label plasma membranes in live HeLa and KB cell culture.
