DETAILS

Description (English)
Application
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 520 maleimide utilized for labeling sulfhydryl (thiol) groups of proteins, especially cysteine residues, to fluorescently study changes in conformation, binding, and kinetics 1,2.
