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 maleimide is suitable for fluorescence labeling of thiol/SH containing molecules.

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...

Benzothiazole dye thioflavin T (ThT) is a sensitive probe for amyloid fibril detection. The ThT probing is based on its unique ability to form highly fluorescent complexes with amyloid and amyloid-like fibrils. In this work we propose an approach of...
