ABBERIOR(R) STAR 580 NHS ESTER (C005B-227593)

General description

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
• 2-color labeling partner with STAR 635P for 2-color STED microscopy

Application

Anti-Mouse IgG-Abberior^® STAR 580 antibody produced in goat has been used for STED (stimulated emission depletion) microscopy in CA3 (Cornus Ammonis) sections. Abberior^® STAR 580 conjugated with secondary antibody has been used for dual-color STED imaging of cultured hippocampal neurons.

Suitability

Designed and tested for fluorescent super-resolution microscopy
