We are happy to offer several products containing the BlackBerry. Quencher (BBQ-650.), which exhibits a broad absorption profile from 550nm to 750nm, centered at 650nm. This range offers more effective quenching of some of our popular long wavelength dyes like TAMRA, Redmond Red, Cy dyes and DyLight dyes. We offer BBQ-650 products for the 3' and 5' termini, as well as BBQ-650-dT for inclusion within the oligonucleotide sequence, with the following properties:
Quenches the fluorescence of long wavelength dyes
Quenches in FRET and contact mode
Absorbance maximum at ~650nm
Quenching range - 550-750nm
Compatible with standard oligo synthesis chemistry
Compatible with regular deprotection but requires mild deprotection with AMA at room temperature
Available for 3', 5', and internal substitution
More stable than BHQ-3
Coupling: A coupling time of 15 minutes is recommended.
Deprotection: Complete the deprotection using the protocol required by the nucleobases. Compatible with standard deprotection conditions in Ammonium Hydroxide and room temperature AMA (Ammonium hydroxide/40% Methylamine 1:1 v/v) for 2 hours.
Anhydrous Acetonitrile/Dichloromethane 1:3 (v/v)
Freezer storage, -10 to -30°C, dry. Light sensitive material.
