Abberior^?STAR 580, NHS ester

半岛bd体育手机客户端 说明

一般描述

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^?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
