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 425 is suitable for preparation of fluorescence labeling reagents.

The fluorescence of the benzothiazole dye thioflavin T (ThT) is a well-known test for amyloid fibril formation. It has now become evident that ThT can also be used for structural investigations of amyloid fibrils and even for the treatment of...

A fluorescent sensor of protein kinase activity has been developed and used to characterize the compartmentalized location of cAMP-dependent protein kinase activity in mitochondria. The sensor functions via a phosphorylation-induced release of a quencher from a peptide-based substrate, producing a...
