Atto 590 (C007B-019798)

Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal speapplication：Atto fluorescent labels are designed for high sensitivity applications, including single-molecule detection. Atto labels have rigid structures that do not show any cis-trans isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.Atto 590 shows a molar extinction of 120,000 and QY of 80% in water (90% in ethanol). Decay time is 3.7 ns.Employed in fluorescence energy transfer, FRET, microscopy.
