General description

Atto 532 is a new label with high molecular absorption (115,000) and quantum yield (0.90) as well as sufficient Stoke′s shift between excitation and emission maximum. It is optimized for excitation with frequency doubled Nd:YAG-Laser, and is characterized by high photostability.


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 532 has been conjugated with the secondary antibodies for STED (stimulated emission depletion) microscopy and immunofluorescence studies.

Hybridization of nucleic acids with secondary structure is involved in many biological processes and technological applications. To gain more insight into its mechanism, we have investigated the kinetics of DNA hybridization/denaturation via fluorescence resonance energy transfer (FRET) on perfectly matched


Fluorescence Lifetime Measurement

Fluorescence lifetime measurement is advantageous over intensity-based measurements. Applications include fluorescence lifetime assays, sensing and FLI.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
