Atto Labels



Atto labels are designed for high sensitivity applications including fluorescence microscopy, flow cytometry, fluorescence in situ hybridization (FISH), receptor binding assays, or enzyme assays. Secondary antibody, streptavidin, and biotin conjugates are available for most of the Atto labels.
  • Spectral data: Emission maxima cover a broad range from 500 to 700 nm
  • Stoke's shift: Shift between absorption maxima and emission maximum is sufficient to discriminate emission from excitation
  • Atto labels exhibit bright fluorescence, extraordinary photostability and good hydrophilicity
