BL 1020
Product Information Molecular Structure


Notes: For installation of a BlackBerry® quencher at the 5'-terminus of an oligonucleotide.

Description: Our BlackBerry® quenchers are excellent quenchers of long-wavelength fluorophores in both FRET and contact modes. They exhibit an absorption maximum at ca. 650 nm and have useful absorbance between 550 and 750 nm. The tricyclic 8-alkoxyjulolidine moiety is a powerful pi-donor that affords a surprising bathochromic shift when compared to related compounds. A key advantage of the BBQ-650® is its stability to ammonia and oxidation conditions. We offer versions for incorporation into oligonucleotides at the 3'-terminus (3'-BBQ-650® CPG, BL 2010), internally (BBQ-650®-dT CEP, BL 1010), or at the 5'-terminus (5'-BBQ-650® CEP, BL 1020 and 5'-BBQ-650®(DMT) CEP, BL 1030). In addition, BBQ-650® NHS Ester (BL 3010) and BBQ-650® TEG azide (BL 3030) are available for postsynthetic labeling of amine-modified oligonucleotides.
