iFluor® 560-dUTP is a iFluor 560-modified nucleotide that can be used in various molecular biology applications, such as labeling and detection of DNA molecules. It contains iFluor 560 dye attached to a deoxyuridine triphosphate (dUTP) molecule via a linker arm. When incorporated into DNA during synthesis, the iFluor® 560-dUTP can be visualized using fluorescence microscopy or other fluorescence-based assays. It is commonly used in techniques such as fluorescence in situ hybridization (FISH), microarray analysis, and real-time PCR. iFluor® 560-dUTP is preferred over other similar fluorescent dyes due to its high fluorescence intensity, photostability, and compatibility with a wide range of detection systems.
