BDP 581/591 NHS ester

BDP 581/591 NHS ester is a a borondipyrromethene dye (Ex=585 nm, Em=594 nm) that has relatively long fluorescence lifetime and two photon excitation cross section. BDP 581/591 NHS ester can be used for fluorescence polarization analysis and also reacts with reactive oxygen species (ROS) and alter fluorescence. BDP 581/591 NHS ester is also an NHS ester derivative that can be used to bind primary and secondary amine groups of proteins, peptides and other molecules.
