BDP 581/591 azide, an azide derivative of the universal, photostable fluorophore BDP 581/591, can be used for conjugation with small molecules and biomolecules to construct tracers for fluorescence polarization assays and microscopy probes [1].
4-Di-2-ASP, a styryl pyridinium fluorescent dye, serves as an essential mitochondrial marker. It effectively and specifically labels pulmonary NEBs (neuroepithelial bodies) [1].
