BDP 581/591 is a borondipyrromethene dye that has relatively long fluorescence lifetime and two photon excitation cross section. It is useful for fluorescence polarization assays. Due to the presence of a diene system, it can react with reactive oxygen species (ROS) with a change of fluorescence. This is the NHS ester derivative for the conjugation with primary and secondary amine groups of proteins, peptides, and other molecules.
