- The Aco-490â„¢ is a water-soluble membrane-labelling dye that can be excited by the violet laser (405 nm).
- When unbound in PBS, the dye remains non-aggregated and exhibits minimal fluorescence signal, effectively reducing false positive results.
- Its fluorescence occurs exclusively upon binding to the lipid bilayer, ensuring high specificity and accuracy.
- Excitation = 405 nm (violet laser), Emission = 458 – 508 nm
