Application

Atto-Farbstoffe wurden entwickelt, um den höchsten Ansprüchen an Sensitivität zu genügen. Eine einmalige Kombination von Vorteilen macht sie zu bevorzugten Werkzeugen für alle Arten von Markierungen . Und einige Eigenschaften bieten besondere Vorzüge in der Einzelmoleküldetektion. Atto-Farbstoffe basieren auf rigiden Strukturen und zeigen keine cis-trans-isomerisierung. Letztere vermindert bei vielen anderen Fluorophoren die Helligkeit des Signals und führt zur Beeinflussbarkeit durch Umweltbedingungen, bspw. zu spektralen Verschiebungen bei der Konjugation.
Atto 565 hat eine molekulare Absorption von 120.000 und einen QY von 92% in Wasser (97% in Ethanol). Die Abklingzeit beträgt 3.4 ns.
Specific and stable fluorescence labeling of histidine-tagged proteins

A combined fluorescence and electrochemical method is described that is used to simultaneously monitor the type-1 copper oxidation state and the nitrite turnover rate of a nitrite reductase (NiR) from Alcaligenes faecalis S-6. The catalytic activity of NiR is measured

Labeling of proteins with fluorescent dyes offers powerful means for monitoring protein interactions in vitro and in live cells. Only a few techniques for noncovalent fluorescence labeling with well-defined localization of the attached dye are currently available. Here, we present

Polarized transport in neurons is fundamental for the formation of neuronal circuitry. A motor domain-containing truncated KIF5 (a kinesin-1) recognizes axonal microtubules, which are enriched in EB1 binding sites, and selectively accumulates at the tips of axons. However, it remains

PTMs of extracellular domains of membrane proteins can influence antibody binding and give rise to ambivalent results. Best proof of protein expression is the use of complementary methods to provide unequivocal evidence. CXCR7, a member of the atypical chemokine receptor

We introduce a general approach for multicolor subdiffraction-resolution fluorescence imaging based on photoswitching of standard organic fluorophores. Photoswitching of ordinary fluorophores such as ATTO520, ATTO565, ATTO655, ATTO680, or ATTO700, i.e. the reversible transition from a fluorescent to a nonfluorescent state
