Atto 520 is a fluorescent label with high molecular absorption (110.000) and quantum yield (0.90) as well as sufficient stoke′s shift (excitation maximum 520 nm, emission maximum 542 nm). It does nearly not show cis-trans-isomerisation, which limits brightness and reproducibility for many other dyes. Due to an insignificant triplet formation rate it is well suited for single molecule detection applications. Can be utilized in applications such as ELISA or immuno-histochemistry, in situ hybridization, flow cytometry and others, to identify streptavidin, avidin, or extravidin-conjugates. Atto-520 fluorescent-labeled biotin can be loaded onto magnetic beads coated with streptavidin through specific ligand–receptor interactions.

Promoter recognition by RNA polymerase is a key point in gene expression and a target of regulation. Bacterial RNA polymerase binds promoters in the form of the holoenzyme, with the σ specificity subunit being primarily responsible for promoter recognition. Free
Protein phosphorylation is a key event in intracellular signal transduction, and fluorescent biosensor for the specific phosphorylation event in a target protein is considered highly useful as a tool of cellular biology and drug screening. Vimentin, the most abundant intermediate

Complex dynamics of combined long-range fluorescence resonance energy transfer (FRET) and short-range electron transfer (ET) processes in a single double-stranded DNA (dsDNA) molecule (see figure) reveals that FRET remains almost unaltered in the presence of ET. Present systems also demonstrate
Three-dimensional fluorescence imaging of thick tissue samples with near-molecular resolution remains a fundamental challenge in the life sciences. To tackle this, we developed tomoSTORM, an approach combining single-molecule localization-based super-resolution microscopy with array tomography of structurally intact brain tissue. Consecutive

Confocal laser scanning microscopy (CLSM) is being increasingly used for observing protein uptake in porous chromatography resins. Recent CLSM studies have revealed the possible existence of a nondiffusive protein transport mechanism. Observing protein uptake with CLSM requires labeling the protein
