BODIPY 630-X, with its unique hydrophobic properties, narrow emission bandwidth, and relatively long excited-state lifetime, is ideal for staining lipids, membranes, and other lipophilic compounds. It is suitable for use in fluorescence polarization assays, two-photon excitation microscopy, and conjugation with various antibodies, peptides, proteins, tracers, and amplification substrates, making it valuable for cell labeling and detection in biomedical research.
