Atto 550 for fluorescence, 90% (HPLC), 1 µg

Atto 550 is a new label with high molecular absorption (120,000) and quantum yield (0.80) as well as sufficient Stokes shift between excitation and emission maximum. Atto 550 can be used with similar excitation source and fluorescence filters as Cy3(R) an 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 spect
