BDPep 630/650 NHS ester

Dicyano BDP 630/650 is a far-red fluorescent dye from the boron dipyrromethene (BDP) family, known for its high brightness and exceptional photostability. Its remarkable stability in strong acidic TFA media makes it particularly suitable for solid-phase peptide synthesis (SPPS). BDPep 630/650 NHS ester can be used for effective cell sorting and phenotyping.
