abberior LIVE 550


Item number
LV550

Description

abberior LIVE 550 is a member of a new class of fluorescent dyes for live-cell imaging exclusively offered by abberior. This dye is highly photostable and bright orange fluorescent dye, which can be effectively excited with a 561 nm laser. For STED, a depletion wavelength between 650 - 775 nm is recommended. Due to the unique isomeric structure the favorited conformation is stabilized, leading to an enhanced cell permeability of the dye. abberior LIVE 550 can therefore be used in very low nanomolar concentration, reducing background and cytotoxicity effectively, allowing long-term STED and confocal imaging of living cells or tissue. Our abberior LIVE 550 is the ideal partner for abberior LIVE 610 to obtain optimal 2 color live-cell STED and confocal results.
