BDP TMR is a borondipyrromethene dye. This is an amine-reactive NHS ester for the labeling of proteins, peptides, and other molecules with amino groups.

BDP TMR is a dye for the TAMRA channel, which is, however, much brighter than TAMRA. Because of the rather long lifetime of the excited state, this fluorophore is a good choice for fluorescence anisotropy measurements, especially with the short linker offered. Fluorescence polarization is an excellent method for high throughput binding assays.
