Fluorescent-labeled DNA is generated through enzymatic incorporation of fluorophore-linked 2'-deoxyribonucleoside-5'-triphosphates (dNTPs) by DNA polymerases. We describe the synthesis of a variety of dye-labeled dNTPs. Amino-linker-modified 5'-triphosphates of all four naturally occurring nucleobases were used as precursors. Commercially available dyes were
Open-top light-sheet microscopy is a technique that can potentially enable rapid ex vivo inspection of large tissue surfaces and volumes. Here, we have optimized an open-top light-sheet (OTLS) microscope and image-processing workflow for the comprehensive examination of surgical margin surfaces

The modification of nucleic acids using nucleotides linked to detectable reporter or functional groups is an important experimental tool in modern molecular biology. This enhances DNA or RNA detection as well as expanding the catalytic repertoire of nucleic acids. Here
Steady-state and time-resolved fluorescence measurements were performed to elucidate the fluorescence quenching of oxazine, rhodamine, carbocyanine, and bora-diaza-indacene dyes by amino acids. Among the natural amino acids, tryptophan exhibits the most pronounced quenching efficiency. Especially, the red-absorbing dyes ATTO 655
