Widely used in bioimaging and fluorescence labeling due to its strong absorption and emission in the visible range. Commonly conjugated to antibodies, nucleic acids, or proteins for detection in techniques like flow cytometry, fluorescence microscopy, and microarray analysis. Its high photostability and quantum yield make it suitable for sensitive detection in biological assays. Often chosen for dual-labeling experiments when paired with other fluorophores due to minimal spectral overlap. Soluble in aqueous buffers and compatible with live-cell imaging under optimized conditions.
