Abberior(R) STAR 580, NHS ester

Descrição detalhada : Abberior STAR 580 is the latest development for STED microscopy with a fluorescent dye in the orange regime. The dye can be excited from 550 to 580 nm. Abberior STAR 580 can substitute dyes like Atto(TM) 590/594 or AlexaFluor 584/594. The dye can most effectively be depleted in STED microscopy at 700 to 780 nm via e.g. a Ti:Sa laser or IR diodes.Abberior STAR 580 is the dye of choice for orange fluorescence. Moreover, the dye is particularly designed and tested for 2-color STED microscopy in combination with Abberior STAR 635 using 2 separate STED wavelength. This offers the great advantage of using 2 regular (not featuring a long Stokes-shift) dyes, which are in general more photostable. Please see our 2-color dye section Key features. Exceptionally bright orange fluorescent dye. Ideal for STED microscopy at 700-775 nm. 2-color labeling partner with STAR 635P for 2-color STED microscopyAbsorption Maximum, lambdamax:: 587 nm (PBS, pH 7.4; water) 584 nm (MeOH, aq.
