BDP TR is a bright and photostable borondipyrromethene dye, which is especially suitable for microscopy applications. The dye has a long excited state lifetime, and is therefore is useful for fluorescence polarization assays. Its large two-photon cross section makes this dye useful for two-photon spectroscopy.
This NHS ester is an amine-reactive form of the dye.
