BP Fluor 680 NHS Ester is a bright and photostable fluorescent dye with an excitation peak at 681 nm and an emission peak at 704 nm. It reacts with the amine group in antibody, proteins, peptides, amino-modified oligos, and other target molecules and is often used for small animal imaging, cytometry, western blot, etc. BP Fluor 680 molecules can be conjugated to proteins at high molar ratios without significant self-quenching.
