ATTO 565

Uses

Atto fluorescent labels are designed for high sensitivity applications, including single-molecule detection. Atto labels have rigid structures th at do not show any cis-trans isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.
Atto 565 shows a molar extinction of 120.000 and QY of 92% in water (97% in ethanol). Decay time is 3.4 ns.', 'Specific and stable fluorescence labeling of histidine-tagged proteins
