Excitation of red-shifted fluorophores with minimal photobleaching for extended imaging sessions.
Ideal for GFP→mCherry FRET pairs. Enables protein-protein interaction studies with minimal cross-excitation.
Reduced phototoxicity enables long-term time-lapse imaging while maintaining cell viability.
Excitation source for PE, PE-Cy5, and other tandem dyes in multi-parameter flow cytometry.
High-resolution 3D imaging with excellent optical sectioning and minimal background fluorescence.
Immunofluorescence assays and diagnostic imaging applications requiring stable, reliable excitation.
The 561nm wavelength optimally excites these red-shifted fluorophores:
The 561nm wavelength provides optimal excitation for red fluorescent proteins while minimizing autofluorescence and phototoxicity compared to shorter wavelengths. This makes it particularly suitable for live cell imaging applications where maintaining cell viability is critical.
